ICRP Publication No. 127, Radiological Protection in Ion Beam Radiotherapy, Ann. ICRP 43 (4), 2014, Y. Yonekura, et al.

The goal of external-beam radiotherapy is to provide precise dose localisation in the treatment volume of the target with minimal damage to the surrounding normal tissue. Radiological protection of medical staff at ion beam radiotherapy facilities requires special attention. Ion beams, such as protons and carbon ions, provide excellent dose distributions due primarily to their finite range, allowing a significant reduction of undesired exposure of normal tissue. Careful treatment planning is required for the given type and localisation of the tumour to be treated in order to maximise treatment efficiency and minimise the dose to normal tissue. Radiation exposure in out of-field volumes arises from secondary neutrons and photons, particle fragments, and photons from activated materials. These unavoidable doses should be considered from the considerations of radiological protection of the patient. Radiological protection and safety management should always be in conformity with the regulatory requirements.

The current regulations for occupational exposures in photon radiotherapy are applicable to ion beam radiotherapy with protons or carbon ions. However, ion beam radiotherapy requires a more complex treatment system than conventional radiotherapy, and appropriate training of staff and suitable quality assurance programmes are recommended to avoid possible accidental exposure of patients, to minimise unnecessary doses to normal tissue, and to minimise occupational exposure of staff (source: www.icrp.org).

ICRP Publication 125, Radiological Protection in Security Screening, Ann. ICRP 43 (2), 2014, D. A. Cool, et al.

The requirement of security screening for individuals and objects has been increasing rapidly, in view of the significant increase in security concerns worldwide. Within the spectrum of technologies used, the application of ionising radiation to provide backscatter and transmission screening capabilities has also increased.

This report provides advice on how the radiological protection principles recommended by the Commission should be applied within the context of security screening.

More specifically, the principles of justification, optimisation of protection, and dose limitation for planned exposure situations are directly applicable to the use of ionising radiation in security screening. In addition, several specific topics are considered in this report, including the situation in which individuals may be exposed because they are concealed ('stowaways') in a cargo container or conveyance that may be subject to screening. The Commission continues to recommend that careful justification of screening should be considered before decisions are made to employ the technology (source: www.icrp.org).

IAEA Publication

International atomic energy agency (IAEA) has brought out a publication entitled "Nuclear Power Reactors in the World" 2015 Edition (ISBN 978–92–0–104915–5; ISSN 1011–2642), Vienna - an annual publication that presents the most recent data pertaining to reactor units in IAEA Member States.

This thirty-fifth edition of Reference Data Series No. 2 provides a detailed comparison of various statistics up to and including 31 December 2014. The tables and figures contain the following information: — General statistics on nuclear reactors in IAEA Member States; — Technical data on specific reactors that are either planned, under construction or operational, or that have been shut down or decommissioned; Performance data on reactors operating in IAEA Member States, as reported to the IAEA. The data compiled in this publication is a product of the IAEA's Power Reactor Information System (PRIS) (Source: www.iaea.org).
