Increased atmosphere radioactivity from the Chernobyl nuclear reactor accident was first detected on air filters taken in Padua on 30 April 1986. Air activities reached the maximum values of 28.6, 19.2, 3.3, 1.7 and 7.5 Bq m-3 for 131I, 132Te(132I), 137Cs, 134Cs and 103Ru respectively, on 1 May; about ten days later the activities declined to less than 1% of peak values. The distribution of radionuclides in Padua was evaluated on the basis of radioactivity measurements detected on natural collectors; it was estimated an average committed dose equivalent to thyroid of 0.37 mSv for adult people in Padua due to 131I inhalation. -English summary

Abstract
Increased atmosphere radioactivity from the Chernobyl nuclear reactor accident was first detected on air filters taken in Padua on 30 April 1986. Air activities reached the maximum values of 28.6, 19.2, 3.3, 1.7 and 7.5 Bq m-3 for 131I, 132Te(132I), 137Cs, 134Cs and 103Ru respectively, on 1 May; about ten days later the activities declined to less than 1% of peak values. The distribution of radionuclides in Padua was evaluated on the basis of radioactivity measurements detected on natural collectors; it was estimated an average committed dose equivalent to thyroid of 0.37 mSv for adult people in Padua due to 131I inhalation. -English summaryI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
