Originally, the IAEA published documents that were used by coimtries as a basis for national regulations and seismic studies. The NS-R-3 (IAEA 2003) contains global requirements for site evaluation. They are intended to ensure adequate protection of site personnel, the public and the environment from the effects of ionizing radiation arising from nuclear installations. 

U.S. radiation protection guidelines are estabHshed by the National CouncH on Radiation Protection and Measurement (NCRP) and are based on the recommendations of the International Commission on Radiological Protection (ICRP). The National Research CouncH also sponsors a report from its advisory committee on the biological effects of ionizing radiations (20).

Since 1925, The International Commission on Radiation Units and Measurements at Bethesda, Maryland has been publishing reports updating the definitions and units for measurements of various radiation-related quantities. Of these ICRU Reports, special mention may be made of reports no. 19 (1971) [radiation quantities and units], 33 (1980) [radiation quantities and units], 36 (1983) [microdosimetry], 47 (1992) [thermoluminiscent dosimetry], and 51 (1993) [radiation protection dosimetry]. A succinct description of various devices used in dosimetry, such as ionization chambers, chemical and solid-state dosimeters, and personnel (pocket) dosimeters, will be found in Spinks and Woods (1990). In this section, we will only consider some chemical dosimeters in a little detail. For a survey of the field the reader is referred to Kase et at, (1985, 1987), McLaughlin (1982), and to the International Atomic Energy Agency (1977). Of the earlier publications, many useful information can still be gleaned from Hine and Brownell (1956), Holm and Berry (1970), and Shapiro (1972). 

Fallen in the hands of criminals, which as a rule have a very remote notion on the danger of ionizing radiation, radioactive sources become a serious threat for the life and health of the terrorists themselves, as well as of casual persons. And the attempt to extract the ampoule with the radioactive source from its protection block is equal to expose oneself to radiation. Besides, in the event of destruction of the ampoule containing radioactive material, radioactive contamination of a large territory can occur. Such an incident happened already in Taromskoe suburb of Dnepropetrovsk.

There are a number of traditional and new control measures to protect consumers from food-borne parasites. Ionizing radiation is one of the new technologies to control or limit the impact of a number of food-bome parasites on public health [10].

There is a long-standing interest in the question of charge and excitation transfer through DNA. This largely resulted from an attempt to protect or to sensitize DNA against the effects of ionizing radiation in radiotherapy. The concept of...

From studies of human populations exposed to certain chemicals, available data are sufficient to characterize the dose-incidence relationships for some types of cancer at high dose levels. However, as in the case of ionizing radiation, the data are not sufficient to define the dose-incidence relationships precisely for any form of cancer over a wide range of doses and dose rates. Therefore, the probability of cancer induction that may be associated with low doses of chemicals that would be of primary concern in protection of public health can be estimated only by interpolation and extrapolation of data at higher doses and dose rates, based on assumptions about the dose-incidence relationships and mechanisms of toxicity. For the few chemicals for which incidence data are available over a range of doses, the dose-incidence relationship is not inconsistent with linearity, but this result does not constitute proof of linearity.
