[Cytogenetic effects in blood lymphocytes of Slavutich residents having no occupational contact with ionizing radiation]. / Tsitogeneticheskie éffekty v limfotsitakh perifericheskoi krovi g. Slavutich, ne imeiushchikh professional'nogo kontakta s ioniziruiushchim izlucheniem.

A comparative cytogenetic examination of the groups of Slavutich and Kiev residents having no occupational contact with ionizing radiation was conducted. It was found a significantly higher chromosome aberration frequency in blood lymphocytes of Slavutich residents (including unstable exchanges--2.5-fold) caused by internal irradiation at the expense of local food stuff consuming. It was revealed no relationship between cytogenetic aberration frequency and initial settling time in Slavutich.

[The biological effects in animals related to the accident at the Chernobyl Atomic Electric Power Station. 1. The experimental model. The radiation loads on animals kept continuously under external and internal radiation exposure in the area of the Chernobyl Atomic Electric Power Station]. / Biologicheskie éffekty u zhivotnykh v sviazi s avariei na Chernobyl'skoi AES. Soobshchenie 1. Model' éksperimenta. Radiatsionnye nagruzki u zhivotnykh, postoianno nakhodivshikhsia v usloviiakh vneshnego i vnutrennego radiatsionnogo vozdeistviia v zone ChAES.

Irradiation conditions in which laboratory animals were kept in experimental laboratories of Chernobyl and Kiev after the accident at the Chernobyl A.P.S. are described. The data are presented on the spectral structural and activity of radionuclides in the diet as well as in the organs and tissues of the animals. The radiation loads have been estimated with regard to an external gamma component and the internal one contributed by the incorporated radionuclides. It has been shown that radiation doses received by the animals during their lifetime due to these contributions do not exceed units of cGy.
