Estimation of external gamma radiation dose in the area of Bory Stobrawskie forests (PL).

Dołhańczuk-Śródka A - Environ Monit Assess (2011)

Bottom Line: The study assessed the radiological risks associated with the presence of natural and artificial radionuclides in the Bory Stobrawskie forests (PL).Using the conversion factors given by UNSCEAR and the measurements results of (232)Th series, (238)U series, (40)K, and (137)Cs specific activities in the 10-cm soil layer the values of absorbed dose (D) and the annual effective dose equivalent derived from terrestrial gamma radiation (E) were calculated.The calculated dose was compared with doses directly measured on the area studied.

Mentions: In Figs. 2 and 3 the distributions of doses calculated from Eqs. 1 and 2 are shown. A gray bar located on the x-axis shows the range that contains 95% of the values. In Table 3 the calculated and measured values of radiation suppose that dose rates are lower than those given in the world average value of 51 nGy/h (UNSCEAR 2000).Fig. 2
