Estimated 137Cs activity during the period from 1100JST(0200UTC) on 12 March 1997 to 1000JST(0100UTC) on 13 March 1997
The contour lines represent 137Cs activity in micro Bq m-3 with log scale from 1 micro Bq m-3, appeared 0 in the figures, to 100000 micro Bq m-3, appeared 5 in the figures, step 0.5.
Then the contour lines show 1, ca. 3, 10, ca. 30, 100, -----, 30000, 100000 micro Bq m-3.
