Although the radiation doses involved in basic research radiology are relatively small, the increasing number of radiological procedures makes risks becoming increasingly high. Quality control techniques in radiological practice have to ensure an adequate system of protection for people exposed to radiation. These techniques belong to a quality assurance program for X-ray machines and are desig...

the radionuclides 226ra, 232th and 40k concentrations measured as well as radiological parameters, for 14 granite samples that use in iran as building material were calculated. the measurements of the radioactivity concentrations were carried out at nuclear physics laboratory university of tabriz. this subject is important in environmental radiological protection, since granites are extensively...

The development of dosimetric concepts and the definition of specific quantities for use in radiation protection has a long history. An important basis for the present concepts was already provided in the 60’s and 70’s by both the International Commission on Radiological Protection (ICRP) and the International Commission on Radiation Units and Measurements (ICRU). In 1991 in its Publication 60 ...

After several years of revision, the International Commission on Radiological Protection, ICRP, recently published the 2007 Recommendations of the Commission (ICRP, 2007). The revision was carried out in a highly participative manner, offering the possibility to comment on various draft versions and provide input in other manners, to international and national organisations as well as to indivi...

Engagement of the radiological protection community in the development of ICRP publications is essential to ensure the best possible system of protection for people and the environment. Normally this means involving a group of experts in the drafting, discussing progress and getting feedback in various forums, seeking comments through a process of open public consultation, and several steps of ...
