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.

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.

State Of Affairs

In the Year of Ecology, announced by the Russian President in the Decree №7, 05/01/16, the authors aim both to draw the attention of the scientific community to the public radiological protection issues concerning radon exposure in Russia and to recognize the neccesity of their resolution. Taking into account the modern scientific evidence on the health impacts of radon and its progenies, the changes of the regulatory approaches to public radiation protection are analyzed. Considering modern challenges in the radon control the current state of affairs in Russia is reviewed. The achieved results in public radiation protection in Russia and new challenges are discussed taking into account new WHO, ICRP and IAEA recommendations. The potential means to improve the current national radon strategy are considered.

Ionising Radiations

Practical Radiation Protection in Healthcare provides a practical guide for medical physicists and others involved with radiation protection in the healthcare environment. The guidance is based on principles set out in current recommendations of the International Commission for Radiological Protection and methods developed by a variety of professional bodies. Written by practitioners experienced in the field, this practical online reference covers both established techniques and new areas of application. This new edition is fully revised and updated to cover new requirements linked to the increased knowledge of radiation effects, and the development of new technology. Each specialist area is covered in a separate chapter to allow easy reference with individual chapters being assigned to different types of non-ionising radiations. Additionally, tabulated data is included to allow the reader to carry out calculations for situations encountered frequently without reference to further resources.
