ObjectivesThe French nuclear worker cohort allows for the assessment of cancer risk associated with occupational radiation exposure, but workers are also exposed to medical and environmental radiation which can be of the same order of magnitude. This study aims to examine the impact of non-occupational radiation exposures on the dose-risk analysis between occupational radiation exposure and cancer mortality.MethodsThe cohort included workers employed before 1995 for at least one year by CEA, AREVA NC or EDF and badge-monitored for external radiation exposure. Monitoring results were used to calculate occupational individual doses. Scenarios of work-related X-ray and environmental exposures were simulated. Poisson regression was used to quantify associations between occupational exposure and cancer mortality adjusting for non-occupational radiation exposure.ResultsThe mean cumulative dose of external occupational radiation was 18.4 mSv among 59 004 workers. Depending on the hypotheses made, the mean cumulative work-related X-ray dose varied between 3.1 and 9.2 mSv and the mean cumulative environmental dose was around 130 mSv. The unadjusted excess relative rate of cancer per Sievert (ERR/Sv) was 0.34 (90% CI −0.44 to 1.24). Adjusting for environmental radiation exposure did not substantially modify this risk coefficient, but it was attenuated by medical exposure (ERR/Sv point estimate between 0.15 and 0.23).ConclusionsOccupational radiation risk estimates were lower when adjusted for work-related X-ray exposures. Environmental exposures had a very slight impact on the occupational exposure risk estimates. In any scenario of non-occupational exposure considered, a positive but insignificant excess cancer risk associated with occupational exposure was observed.

Although many interventions involving radiation exposure have been replaced to endoscopic procedure in the gastrointestinal and hepatobiliary fields, there remains no alternative for enteroscopy and endoscopic retrograde cholangiopancreatography (ERCP), which requires the use of radiation. In this review, we discuss the radiation doses and protective measures of endoscopic procedures, especially for ERCP. For the patient radiation dose, the average dose area product for diagnostic ERCP was 14–26 Gy.cm², while it increased to as high as 67–89 Gy.cm² for therapeutic ERCP. The corresponding entrance skin doses for diagnostic and therapeutic ERCP were 90 and 250 mGy, respectively. The mean effective doses were 3– 6 mSv for diagnostic ERCP and 12–20 mSv for therapeutic ERCP. For the occupational radiation dose, the typical doses were 94 μGy and 75 μGy for the eye and neck, respectively. However, with an over-couch-type X-ray unit, the eye and neck doses reached as high as 550 and 450 μGy, with maximal doses of up to 2.8 and 2.4 mGy/procedure, respectively. A protective lead shield was effective for an over couch X-ray tube unit. It lowered scattered radiation by up to 89.1% in a phantom study. In actual measurements, the radiation exposure of the endoscopist closest to the unit was reduced to approximately 12%. In conclusion, there is a clear need for raising awareness among medical personnel involved endoscopic procedures to minimise radiation risks to both the patients and staff.

One source of radiation is X-ray aircraft, which utilization must pay attention to safety aspects. Room design is the first step that must be done before the operation of X-ray aircraft. Radiology Unit Kasih Ibu Kedonganan Hospital operates an X-ray aircraft with specifications of 250 kV-85 mA, needs to be tested for radiation exposure which is an integral part of the verification of radiation protection. Test for radiation exposure at least once a year. The purpose of the installation room design is to ensure that workers or the general public around the plant receive radiation exposure that is smaller than the applicable dose limit value (DLV), by the radiation safety provisions that refer to the Decree. BAPETEN No. 7 of 2009 concerning Radiation Safety in the use of radiographic equipment. This study will test exposure to room wall shields associated with radiation workers and the general public. The results showed that all walls A, B, C, D, and E could still completely weaken the rate of X-ray radiation. The highest radiation dose detected on wall B is the primary wall for the Buky stand examination.

Introduction: Health development in Indonesia is influenced by the increasing needs and demands of the community to obtain quality health services. Progress in health service facilities as a form of the use of radiation beams. The utilization of radiation substances in the field of health care is a source of danger for radiation workers in the radiology department. X-ray radiation has an impact on human health, especially the health of radiographers. The purpose of this study was to analyze the increase in leukocytes due to X-ray radiation exposure in workers exposed (radiographers) with unexposed workers (admissions officers) at the Jemursari Islamic Hospital in Surabaya. Methods: This study used an analytic observational study, using a cross sectional research design, and the analysis used was the independent t-test and mann whitney. Research subjects numbered 18 respondents taken from the population in accordance with specified criteria. Result and Discussion: The results showed there was no difference between exposed workers (radiographers) and unexposed workers (admissions officers) on increased leukocytes due to X-ray radiation exposure. Lymphocyte variables were not significantly different (independent t-test p = 0.137), monocyte variable no significant difference (independent t-test p = 0.525), neutrophil variable no significant difference (independent t-test p = 0.137), eosinophil variable no significant difference (mann whitney p = 0.27), there is no significant difference in the basophile variable (independent t-test p = 0.738). Conclusion:X-ray radiation exposure does not affect the increase in leukocytes in the blood in radiology workers.

Abstract Objective To explore the sensitivity index of radiation injury of radiation workers was analyzed and investigate whether the body changes and radiation doses of workers exposed to low-dose radiation have a dose-effect relationship. Methods The occupational health monitoring data of radiology staff were analyzed by retrospectively. Results Individual dose monitoring data, interventional radiology workers had the highest average cumulative annual dose, 0.86mSv. Lens opacity has a high detection rate, Compared with the control group, the lymphocyte count was increased. Annual cumulative dose reached 2.04 mSv, and single cycle average dose reached 1.62 mSv, dicentric chromosome was detected. Conclusions Radiation workers have certain radiation damage, and the focus is on those engaged in interventional radiology. The chromosome aberration rate was highest in people with more than 20 years of working life. Annual cumulative dose reached 2.04 mSv, and single cycle average dose reached 1.62 mSv, dicentric chromosome was detected, it suggests that the chromosome aberration analysis is an important index in occupational health monitoring of radiological workers.

BACKGROUND: A primary consideration in any radiographic procedure is to reduce the dose to the patient and the operator while still achieving the diagnostic goals. OBJECTIVE: To study the radiation exposure and protective measures in different units of various hospitals in Kashmir valley in compliance to recommendations from regulatory authorities. METHODS: Twenty-eight stationary X-ray units of various major hospitals of the Kashmir Valley were surveyed by the radiation safety group of SKIMS. Panoramic survey meter, Thyac-V survey meter-470A, Prima-7 digital survey meters were used for radiation exposure estimations. The radiation level measurements were carried out at different critical locations like control console, door and the corridor adjacent to the Diagnostic equipment and were compared with the standards of AERB and IAEA. RESULTS: Of the 28 stationary X-Ray units identified 21 were functional and surveyed. Seventy seven Radiation workers (Technicians) operating these units perform about 1335 diagnostic procedures daily on these units. Out of 21 X-ray units surveyed, 9 (42.86%) had dose rate at the control panel within the permissible limits and 12(57.14%) had exposure levels higher than permissible limits. The dose levels at the door and corridor were exceeding the permissible limits in all the units. Most of the radiation workers had no concept of radiation protective measures and did not use any personal radiation monitoring device like TLD (Thermo-luminescent dosimeter). CONCLUSIONS: To avoid radiation exposure, the radiation safety measures ought to be strictly followed which is possible by making the concerned authorities answerable and accountable. Also the radiation workers need to be made aware of hazards of radiation exposure, importance of using personnel monitoring devices and providing knowledge about the safety measures.

Poor implementation of quality assurance programs in the radiation industry has been a major setback in our locality. Several studies revealed that occupational workers are exposed to many potential hazards of ionizing radiation during radio-diagnostic procedures, yet radiation workers are often not monitored. This study aims to evaluate the occupational exposure of the radiation workers in Federal Medical Centre Katsina, and to compare the exposure with recommended occupational radiation dose limits. The quarterly readings of 20 thermo-luminescent dosimeters (TLDs') used by the radiation workers from January to December, 2019 were collected from the facility's radiation monitoring archive, and subsequently assessed and analyzed. The results indicate that the average annual equivalent dose per occupational worker range from 0.74 to 1.20 mSv and 1.28 to 2.21 mSv for skin surface and deep skin dose, measured at 10 mm and 0.07 mm tissue depth respectively. The occupational dose was within the recommended national and international limits of 5 mSv per annum or an average of 20 mSv in 5 years. Therefore, there was no significant radiation exposure to all the occupational workers in the study area. Though, the occupational radiation dose is within recommended limit, this does not eliminate stochastic effect of radiation. The study recommended that the occupational workers should adhere and strictly comply with the principles of radiation protection which includes distance, short exposure time, shielding and proper monitoring of dose limits. Furthermore, continuous training of the radiation workers is advised.
