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.
