Radiation Protection in major research-facilities includes several aspects concerning their planning, the hazard-sources, the environmental protection and the general safety. The present paper includes a concise presentation of the approach to the radiation protection policies proposed for the Athens Race Track Microtron (250 MeV, 550 mA) and the Heraclion Modified Betatron Accelerator (25 MeV, 1 kA).

Abstract As chest x rays involve risks of patients falling, radiologic technologists (technologists) commonly assist patients, and as the assistance takes place near the patients, the eye lenses of the technologists are exposed to radiation. The recommendations of the International Commission on Radiological Protection suggest that the risk of developing cataracts due to lens exposure is high, and this makes it necessary to reduce and minimize the exposure. The present study investigated the positions of technologists assisting patients that will minimize exposure of the eye lens to radiation. The results showed that it is possible to reduce the exposure by assisting from the following positions: 50% at the sides rather than diagonally behind, 10% at the right side of the patient rather than the left and 40% at 250 mm away from the patient. The maximum reduction with radiation protection glasses was 54% with 0.07 mmPb and 72% with 0.88 mmPb.

Total Effective Dose

The paper reviews the efficience of radiation protection in uranium mining industry. The officially provided data on individual doses for underground and surface mining professionals is analysed and cancer morbity risk is assessed. The researchers defined the individual components of the total effective dose and separately assessed their contributions. The total of 114 cancer cases have been registered during the past 15 years. Accumulated equivalent doses for lungs are estimated from 20 to 430 mSv. The total working time in 56% of individual cancer cases diagnosed made over 20 years. The actual lung cancer mortality rate for miners is established 3 cases per 1000 individuals, which permits to question the authenticity of the dosimetric data and the efficiency of radiological protection applied.
