Increased T-cell receptor mutation frequency in radiation-exposed residents living near the Semipalatinsk nuclear test site.

Abstract excerpt

From 1949 to 1989, 488 nuclear explosions were carried out in Semipalatinsk, and the cancer risk is increased in this region. Measuring somatic-cell mutation frequencies may be a useful tool for evaluating cancer risk within radiation-exposed populations. Here, we report the first evidence of increased T-cell receptor (TCR) mutations in peripheral blood from radiation-exposed residents of Semipalatinsk. The TCR...
