An exponential decline of radioactivity followed the moratorium on atmospheric nuclear testing. The highest activity of Sr-90 deposited by fallout, being 1060 Bq/m2, was recorded in 1963, while the peak Sr-90 activity concentration in milk, 1.42 +/-0.17 Bq/L, was recorded in 1964. The values in year 2001 for fallout deposition and milk were 7.7 Bq/m2 and 0.07 +/- 0.03 Bq/L, respectively. The reactor accident at Chernobyl caused higher Sr-90 levels only in 1986.
