Abstract (en)

After the investigation of pine from Vilnius County there were the following mean specific activities of investigated radionuclides determined in timber by 1 m from floor: 15.9 ± 4.5 Bq/kg (137Cs), 245 ± 26 Bq/kg (40K), 5.6 ± 1.2 Bq/kg (226Ra), 12.2 ± 3.2 Bq/kg (232Th). The following mean specific activities of radionuclides were determined in pine timber from Alytus County: 2.4 ± 0.5 Bq/kg (137Cs), 162 ± 33 Bq/kg (40K), 0.9 ± 0.3 Bq/kg (226Ra), 1.1 ± 0.4 Bq/kg (232Th). In pine timber from Kairiai there were the following specific activities of investigated radionuclides determined: 3.7 ± 1.3 Bq/kg (137Cs), 9.6 ± 2.4 Bq/kg (40K), 3.8 ± 0.6 Bq/kg (226Ra), 19.4 ± 1.4 Bq/kg (232Th).
