LONG-TERM Kr-85 AND Xe-133 CONCENTRATION IN LOWER ATMOSPHERE MEASUREMENTS
For about 30 years our Laboratory
develops the instruments and methods for Kr and Xe atmospheric
radioactivity measurements. The regular measurements of Kr and
Xe in the air have been conducted up to 1990 with the equipment
developed. The 133 Xe atmospheric activity data (Ci/liter of the
air) vs time is presented here to illustrate the results we have
obtained. The air samples were taken in the vicinity of Mariupol
(ex-Zhdanov) town on the Azov sea.
