Gross β activity level of fallout in the environment around Qinshan Nuclear Power Plant

This paper presents the measurement results of gross β activities in fallout samples collected from the environment around Qinshan Nuclear Power Plant (NPP) during 1993-2002. The gross β activity of 191 samples collected at five monitoring spots were (0.11～3.64) Bq · m-2 · d-1, with an average of (0.91 ±0.49) Bq · m-2 · d-1. This value was lower than (1.02±0.35) Bq·m-2·d-1 , the average of the samples collected at the reference spot in Hangzhou.It indicated that no obvious rise in the gross β activity level of fallout was observed in ambience of Qinshan NPP.
