The 137Cs bulk deposition samples measured in samples collected at Cluj-Napoca in 1965–1985 are analysed and compared with published 137Cs deposition data from New-York, St. Petersburg, Helsinki and Bratislava covering partially/totally the period 1955–1985. A total 137Cs deposition of 4.2 ± 0.9 kBq/m2 at Cluj-Napoca is estimated for 1955–1985 based on the comparison of available data. The signature of the atmospheric nuclear tests performed in 1977–1980 is presented using the monthly measured bulk depositions of 106Ru, 125Sb, 137Cs and 144Ce (1978–1982) and 95Zr, 103Ru, 141Ce for the year 1981, following the last atmospheric nuclear test of October 16, 1980.

对 1965-1985 年在 Cluj-Napoca 采集的样品中测量的 137Cs 大块沉积样品进行了分析,并与来自纽约、圣彼得堡、赫尔辛基和布拉迪斯拉发的 1955-1985 年部分/全部期间公布的 137Cs 沉积数据进行了比较。根据可用数据的比较,估计 1955-1985 年在 Cluj-Napoca 的 137Cs 总沉积量为 4.2 ± 0.9 kBq/m2。1977-1980 年进行的大气核试验的特征是使用 1981 年上一次大气核试验之后的 106Ru、125Sb、137Cs 和 144Ce(1978-1982)和 95Zr、103Ru、141Ce 的月度沉积量来呈现的1980 年 10 月 16 日。
