Justification of the methodical approaches to the assessment of the doses of the public residing in the zone of influence of the facilities of the nuclear and radiation legacy

To justify the decision on the necessity of the execution of the remediation actions or public safety measures as well as the correspondence of the remediated territories to the established criteria or reference levels it is necessary to correctly perform the assessment of the doses of the public residing in the zone of influence of the facilities of the nuclear and radiation legacy. Currently, there is no legislative document, regulating the doses of that category of the public. Based on the result of the regulatory documents and scientific publications on the radiation surveys of the contaminated territories and assessment of the doses to the public residing in the surveillance zone of the radiation facilities, on the radioactively contaminated territories and exposed by natural radionuclides, it was estimated that approaches, models and equations for the estimation of the doses from man-made and natural radionuclides can be applied for the public residing in the zone of influence of the facilities of the nuclear and radiation legacy. The number of control measurement points and samples for the radiation survey of the territories of the limited scale should be sufficient for the representative assessment of the doses to the public.
