Because of the diversity of apparatus for the generation of ionizing radiations and the significant differences that exist between laboratories within and between countries, it is not possible to give other than general guidelines as to the preventative measures to be taken.

It will be assumed here that the most likely sources of exposure will be X-ray generators and radioisotopes used in the manufacture of specimens for Mössbauer and NMRON use, for example. The basis for this assumption is the belief that establishments maintaining neutron and particle accelerator sources will have local regulations more stringent than those of the country in which they exist – certainly more stringent than those suggested in ICRP-26. They will also have a radiation protection officer who will discharge a list of duties similar to those stated in Subsection 10.1.3.2 .
