The new methods of passport doses calculating presented in the work involves the use of a model whose parameters are determined by the types, quality and completeness of radio-ecological and dosimetric monitoring carried out on the radioactively contaminated territories in 1986-2013.

At the same time, an important problem is the development of pathological changes in the heart in the longterm period, which worsen the quality of life and increase the risk of cardiac death 10 or more years after RT The problem of heart damage due to RT is gaining new significance due to the existing increase in the number of cancer patients requiring radiation exposure in the modern world. RT of malignant tumors of the breast and organs of the chest cavity causes damage to all structures of the heart, including the coronary arteries, valves, conducting system, pericardium. The frequency of heart damage increases in proportion to the time that has passed after RT. According to some authors, the prevalence of clinically significant radiationinduced heart diseases 5-10 years after RT is 10-30%, and the frequency of asymptomatic lesions is 88%. The duration of the latent period can reach 15-20 years. The work has an analysis of longterm studies of the presence of pathological changes that are found in the heart tissues of patients with breast cancer, as a result of radiation therapy.</p>","PeriodicalId":20491,"journal":{"name":"Problemy radiatsiinoi medytsyny ta radiobiolohii","volume":"27 ","pages":"60-83"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10460680","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}
