Determination of137Cs and134Cs in air samples collected near Belgrade /Yugoslavia/ following the Chernobyl accident

Air Radioactivity Monitoring in Serbia

“…Ceasium-137 had specific seasonal pattern following total beta activity seasonal variations (Fig.3. ) (Smiljanic et al, 1989;Todorovic et al, 1996;Todorovic et al, 1997). www.intechopen.com (1) maximum daily activities (30 minutes sampling period), (2) sampling on coal filter * NaJ(Tl) detector, well-type.…”

“…Average daily air radioactivity in May 1986, Institute Vinca (Smiljanic et al, 1989) In May 1986, only about 30% of the total iodine released in the atmosphere could be detected in the aerosols filters. Other 36% of elemental iodine and less active organic www.intechopen.com compounds was detected by coal impregnated filter and the rest 34% of active organic compounds by active coal Smiljanic et al, 1989;Andrasi, 1986). The data on the activity of plutonium in air in the period of intensive nuclear weapon tests in 1965-1969 are presented in Table 2.…”
