trailer Review how radiation is measured, and understand the concept of radiation's half-life value. There are several comprehensive guidelines that provide useful information on operational requirements for radiation protection. According to the ICRP (Publication 103), the System of Radiological Protection is based on the . The effective dose isthe sum over theentire body of the individual organ equivalent doses and is expressed in millisieverts (mSv). More frequent monitoring of radiation dose is usually implemented in order to check more regularly against the dose limit. 0000175176 00000 n 0000623862 00000 n The International Atomic Energy Agency (IAEA) neatly packages these into the 10 pearls for radiation protection of the patient and staff, which are summarized below. The lead equivalence should be first checked by a medical physicist to ensure that sufficient protection is provided. 0000623442 00000 n Termination of pregnancy should not be considered at doses below 100 mGy and even above this threshold consideration needs to be given to the gestational age at exposure and the dose. Real-time dosimetry systems are useful. vo(UH.BXyo~e2wBt However, the doses from these acute exposures were delivered much faster (higher dose rate), were high linear energy transfer radiation, and in a higher dose range (much greater than 100 millisieverts [mSv]) than is typically delivered in a diagnostic or interventional medical imaging procedure. Simple interventions can play a major role in radiation dose optimization. Internal radiation therapy, or brachytherapy, is a form of nuclear medicine treatment where radiation is released from inside the body for treatment of cancer, such as non-Hodgkin lymphoma. 0000175728 00000 n Unfortunately, in a significant number of healthcare settings, there is a paucity of monitoring and, thus, a lack of reliable data. Radiation Protection of Patients (RPOP) - the leading resource for health professionals, patients and public on the safe and effective use of radiation in medicine. 2014 Dec [PubMed PMID: 25088230], Lpez PO,Dauer LT,Loose R,Martin CJ,Miller DL,Va E,Doruff M,Padovani R,Massera G,Yoder C, ICRP Publication 139: Occupational Radiological Protection in Interventional Procedures. It is essential to recognize that this is a population risk rather than specific to an individual.

On this page: Time, distance and shielding Keep records of fluoroscopy time and, if available, dose area product/kerma area product for every patient. stream Aprons and collars should be checked annually for lead integrity . [16]Brachytherapy comes with its side effects, which differ from ionizing radiation from medical imaging. Repair begins immediately, with opportunity for full repair or misrepair resulting in chromosomal aberrations. It includes all radiation exposure from both fluoroscopy screening and acquisition runs. 1 0 obj It includes contributions from both the primary x-ray beam and from scattered radiation (including backscatter from the patient). Leaded eyeglasses and should be at least 0.25 mm lead equivalents to provide adequate protection for the lens of the eye. The radiation also can't be easily transmitted to others, experts say. The IAEA provides a collation of these coefficients, which include 0.26 mSv/Gycm 2 for percutaneous transluminal angioplasty (PTA), most embolizations, and transjugular intrahepatic portosystemic shunt (TIPS) procedures and 0.12 mSv/Gycm 2 for pulmonary angiography with filter and bronchial artery embolization.

Minimize number of frames and cine runs to clinically acceptable level Avoid using the acquisition mode for fluoroscopy Cine dose rate (10-60) normal fluoroscopy The equivalent dose is calculated, taking into account the organ-specific radiation exposure, as well as the organ's sensitivity to radiation, and isexpressed in millisieverts (mSv). 10 Pearls: Radiation protection for children in interventional procedures 4. Make good use of the time, distance, shielding principle: minimize time, maximize distance, utilize shielding. 0000004369 00000 n This can be addressed by using an antifog spray (similar to those used for diving goggles) and ensuring that the surgical mask makes good contact with the nose to prevent air rising and fogging the glasses. 0000003921 00000 n Radiation and for the Safety of Radiation Sources (IAEA Safety Series No. reported that as much as 50% of physicians do not wear or incorrectly wear dosimeters. 0000624282 00000 n endstream endobj 337 0 obj <>/Size 232/Type/XRef>>stream It is estimated that a significant number of imaging examinations are unnecessary Consultation between the referring physician and the radiologist is recommended 2. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 29 0 R 30 0 R 51 0 R 57 0 R] /MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> 3 0 obj [14]Interestingly, the opacification of the posterior lens, in comparison to the other locations, is relatively specific to radiation exposure. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 60 0 R 61 0 R] /MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> 2 0 obj The type of nose pad/bridge of the glasses will affect comfort based on individual preference. For an interventionalist, the full range of personal protective equipment available and recommended can be burdensome, particularly for the duration that it needs to be worn. It is simple to have some small squares (e.g., approximately 88 cm) of lead (0.1 mm thick) and place these next to the apron in multiples of 0.1 mm when being screened. Radiation exposure from various nuclear power plants has allowed us to develop basic principles of radiation protection to ensure the safety of employees and how to handle unplanned exposures. These are typically evident on a much shorter time frame than stochastic effects and occur above a threshold and hence are not probabilistic in nature. Why should multiple pass of phase CT be performed routinely? Position yourself on the side of the transmitted beam (i.e., by the imaging receptor/detector), where radiation levels are much lower after being attenuated by the patients body. eg. 0000621509 00000 n Use personal dosimetry (see further discussion in the Dosimetry section). 0000175431 00000 n Address your concerns about radiation protection to radiation protection specialists (e.g., medical physicists, radiation safety/protection officers). <>/PageLabels 300 0 R>> Because of the level of potential radiation exposure for interventionalists, you should always wear, at a minimum, one personal dosimeter on the inside of the protective apron at chest level. 2 0 obj 0000570261 00000 n Radiation exposure can come from many sources including X-rays, radioactive materials, nuclear power plants, and radioactive waste sites like Hanford. These regulations apply to operators of nuclear power plants, as well as industrial and medical facilities licensed to use man-made radioactive materials. 0000623493 00000 n 0000622913 00000 n Typically, it is not measured directly or displayed during a procedure, although some manufacturers are starting to offer optional software that does provide peak skin dose information. Minimize distance between the patient and the image receptor. Aprons that wrap circumferentially around the body are preferred to front aprons, given their increased surface area coverage. The risk coefficient for fatal cancer is, at most, a few times the population as a whole. 0000570234 00000 n 0000336734 00000 n Radiation Protection of Staff (IAEA 10 Pearls) : Use protective equipment (discussed in detail in the Protective Equipment section).

The flexibility of an EMF protection tool is also another essential thing that you must consider. Remember: Some tissues of a growing child are more sensitive to radiation than adult Children have longer life span to manifest radiation effects As doses increase above the threshold the severity of the effect also increases. 0000005095 00000 n Protocol development and education strategies have been effective in multiple specialties. These effects, if occurring, are relevant to patient exposure of the heart and brain in complex interventional procedures where doses may exceed these values. 0000623274 00000 n The most common adverse reactions are thrombocytopenia, neutropenia, fatigue, nausea, vomiting, diarrhea. The image intensifier or x-ray plate should be as close to the patient as possible, with the x-ray tube positioned as far away as possible while maintaining adequate image resolution. 0000624028 00000 n 0000006775 00000 n 0000004145 00000 n It is difficult to show a causal connection with radiation and cancer directly in either patient groups undergoing medical imaging or staff who have been occupationally exposed. 0000621941 00000 n On the other hand, AK depends on the distance from the x-ray tube and is expressed at the interventional reference point (IRP). To approximate effective dose, the DAP/KAP can be multiplied by a conversion coefficient. These are believed to be due to elevated circulating reactive oxygen species resulting in a chronic low-grade inflammatory state. 115) is provided in three interrelated Safety Guides (IAEA Safety Standards Series No. The absorbed dose is the radiation deposited in an object and is measured in milligrays (mGy). The annual limit for the hands and the feet is 500 mSv. From these studies the concept of the linear no threshold model has evolved. The disposable pads may also lead to a reduction in interventionalist hand dose, depending on positioning. An understanding of these definitions is critical to interpreting dose recommendations. Radiation insult leads to activation of a response through protein kinase, predominantly by ataxia-telangiectasia-mutated (ATM), which causes phosphorylation of the histone H2AX producing -H2AX. The staffs positioning when carrying out these tasks may mean that they are not protected by any additional in-room lead shields. [13]Studies have shown a relationship between occupational radiation doses and cataract development before 50 in a large cohort of radiation technologists, specifically the posterior lens. On most modern machines, virtual collimation allows you to simulate the collimation on a static image so that it can be adjusted without the use of radiation. 2 0 obj However, there is potentially a lack of understanding or knowledge regarding fetal irradiation because often the medical exposure of a pregnant patient will be readily justified. Why don't they particularly want high quality/ crisp images in CT, instead using images with some noise without loss of diagnostic information. New Poster! The first step to optimizing safe radiation practice is educating hospital staff on radiation best practices. %PDF-1.5 Velauthapillai etal. 0000174773 00000 n Aprons made of lead material typically last 10 years when well cared for (hung appropriately and cleaned). <> 0000003154 00000 n startxref 0000005369 00000 n A follow-up step might be to offer potentially at-risk interventionalists and trainees access to genetic screening for germline mutations (likely including mutation types in BRCA1, BRCA2, and MLH1, among others) that increase susceptibility to radiation-induced DNA damage. The first step would be to look at family cancer history and to identify high-risk populations. X-rays are composed of high-energy photons within the electromagnetic spectrum. It is likely that an interventionalist may need to perform a procedure on a pregnant patient during their career. [3]For reference, 20 mSv/year roughly equates to2 to 3 abdominal and pelvic computed tomography (CT) scans or7TO 9 years of background radiation. There has been increasing interest in brain caps with lead equivalence to reduce the risk of intracranial malignancy by shielding the head. Keep hands outside the primary beam unless totally unavoidable Hands inside the central area of the primary beam will increase exposure factors (kV, mA) and doses to patient and staff Thyroid protection Lead glass eyewear with side protection 1. The additional dose due to backscatter can be up to 50% (typically around 30%), depending on the beam quality (energy and filtration of the x-ray beam) and the beam area. ;E?6ENy7z_9. Table 5.1 shows how to convert the displayed DAP/KAP quantity to gray per square centimeter if necessary. Some fluoroscopy suites contain ceiling-suspended lead acrylic shields, which can reduce doses to the head and neck by a factor of 10. Radiation safety is a concern for patients, physicians, and staff in many departments, including radiology, interventional cardiology, and surgery. 2012 Nov; [PubMed PMID: 22832138], Lin Y, Internal radiation therapy: a neglected aspect of nuclear medicine in the molecular era. It is important to ensure that the apron is a good fit, both ergonomically and for radiation protection. It is more effective to use the ceiling shield . At a cellular level, radiation exposure can cause direct damage to DNA resulting in double- or single-stranded breaks (lesions) or indirect damage through the production of reactive oxygen species that also lead to DNA damage. It is not common practice to use leg/tibial shields, and the undertable protective drapes provide significant attenuation of scatter reaching the lower extremities of the interventionalist that are not shielded by the standard lead apron, although others have commented on their routine use. Increasing the distance between the x-ray beam and the part that is being imaged is another way to minimize exposure. 0000003295 00000 n Despite the difficulty in performing invivo research in this area, a recent study using blood samples taken from interventionalists before and after performing image-guided endovascular aneurysm repair (EVAR) cases showed that levels of both -H2AX and pATM increased significantly. 10 Pearls: Radiation protection of patients in fluoroscopy Image receptor Image receptor Image receptor Pulsed fluoroscopy reduces exposure X ray pulses 1 second. This provides better protection from scattered dose. 0000622695 00000 n Lead garments should be checked every six months to assure their integrity, and leaded aprons should be hung rather than folded to prevent cracking. Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. In comparison, there is a chance that a specificx-raycauses DNA damage that later develops into cancer, a stochastic effect. 0000000016 00000 n What are some simple ways to notify patients to inform the tech of possible pregnancy?

Radioactive Materials - Licenses and inspects radioactive materials used in industry, research, healthcare. dCv> - Make good use of the time, distance, shielding principle: minimize time, maximize distance, utilize shielding. Facilities should ensure that there are some common-use lead glasses available (and overglasses for those staff wearing ordinary prescription glasses). The interventionalist is positioned closest to the anatomy being imaged and receives the majority of their exposure from x-ray radiation scattering from the patient. These coefficients can vary considerably because they depend on the x-ray equipment, x-ray beam quality, size of the patient, and area of the body being exposed. Doses above 100 mGy, especially doses above 150 mGy, are viewed as the minimum amount of dosage at which negative fetal consequences will occur, based on observation. 0000008939 00000 n 0000257759 00000 n '>.^4D\B1e!.

It is not necessary to use additional lead aprons (and is most likely counterproductive because of the physical weight). Some of these provide visual feedback, which can assist in proactively reducing exposure. As radiation exposure becomes more prevalent, a thorough understanding ofradiation exposure risks and dose reduction techniques will be of utmost importance. Minimize number of frames and cine runs to clinically acceptable level Avoid using the acquisition [15]Dosimeters should be worn both outside and inside the leaded apron for comparison of doses, and the readings should be analyzed by the facilitys radiation safety department. Explore Radiation Topics - Nuclear energy, radiation emergencies, radon, Hanford, and more. Typically, measures that reduce the dose to the patient also reduce the dose to staff. Interestingly, there is no direct evidence of heritable effects in human studies, although experiments with animals have shown otherwise. However, this is difficult to prove because it would require long-term follow-up through epidemiologic studies. It is worth considering. 232 107 0000002485 00000 n Radiation protection of patients in fluoroscopy Find this poster in PDF format at:. 0000624005 00000 n Good technique= _____ slices only when necessary, Pay attention to radiation dose values and compare with _________ ____________ __________ (___), Be aware of CT dose ______ and recommended dose levels for different body regions, Exam: CT head endstream endobj 233 0 obj <>/Metadata 26 0 R/Pages 25 0 R/StructTreeRoot 28 0 R/Type/Catalog/Lang(en-GB)/PageLabels 24 0 R>> endobj 234 0 obj <>/MediaBox[0 0 595.32 841.92]/Resources<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI]/ExtGState<>>>/Type/Page>> endobj 235 0 obj <>/A<>/F 4/StructParent 1>> endobj 236 0 obj <>/A<>/F 4/StructParent 2>> endobj 237 0 obj <> endobj 238 0 obj <> endobj 239 0 obj [263 0 R] endobj 240 0 obj <>stream Only procedures that have been justified as having a net benefit for the patient when considering the radiation risks should be undertaken and all appropriate steps taken to obtain informed patient consent. 0000092961 00000 n The ICRP's dose recommendations are shown in fig 1.
