For radiation objects of different categories of potential radiation hazard, it is largely the same. In all cases, it is required to issue a sanitary and epidemiological conclusion on the compliance of working conditions with ionizing radiation sources with sanitary rules and licenses, which in this case practically duplicate each other. As one of the possible ways to ensure greater differentiation of regulatory requirements taking into account the real danger of various sources, the formation of a three-level system of sanitary and epidemiological regulation of the use of technogenic sources of ionizing radiation is proposed. The first level is radiation equipment products, the radiation doses of people due to the use of which cannot exceed the established hygienic standards for the population under any conditions of the use for which these products are designed. Their handling is exempt from regulatory control and should be carried out as with products that do not pose a radiation hazard. The second level is radiation technology products that do not pose a serious potential radiation hazard to people, but require certain regulation of their handling to ensure a socially acceptable level of radiation safety. Handling of them is allowed in the presence of sanitary and epidemiological conclusion, and a simplified radiation monitoring system may be allowed. The third level is the products of radiation technology that pose a significant potential radiation hazard to humans. A serious harm to human health is possible in case of violations of the rules for handling such products and in the event of a radiation accident. Handling them is allowed if there is a sanitary and epi- demiological conclusion and a license. Such an approach, while maintaining the achieved level of radiation safety, will significantly simplify the regulatory system and eliminate unreasonable obstacles to the expanded use of radiation technology. It is also necessary to consider the possibility of developing special standards to ensure sanitary and epidemiological requirements of the use of mobile and mobile medical diagnostics using sources of ionizing radiation. The absence of such standards hinders the implementation of modern methods of X-ray diagnostics.","PeriodicalId":496413,"journal":{"name":"Радиационная гигиена","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136344146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the studies was to analyze the information describing changes in the 137 Cs concentrations in agricultural animal forage: hay, haylage, silage and green fodder in the southwestern districts of the Bryansk region affected by the contamination after the ChNPP accident. The data on countermeasures in the fodder production are given and the system of radiological monitoring of fodder contamination is described. It is shown that the dynamics of changes in the 137 Cs concentrations in fodder was mainly determined by the dynamics of implementation of remedial measures. The effective halflives of 137 Cs concentration in forages during the first period after the accident (1987-1990) varied from 0.57 to 2.7 years. Subsequently (1991-2021) the decrease in feed contamination slowed down and the half-lives ranged from 8.0 to 50.0 years and longer depending on the scope of remediation and the characteristics of the plants used for the animal feed production.","PeriodicalId":496413,"journal":{"name":"Радиационная гигиена","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136005188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
