| Abstract: | Increased atmospheric radioactivity from the Chernobyl accident was first detected on air filters taken in Monaco on 30 April 1986, with maximum activities of 10, 2·9, 1·5 and 0·84 Bqmdash3 for 132Te, 131 I, 137Cs and 134Cs, respectively, occurring about 1–3 May 1986. About one week later the activities had fallen to about 1% of peak values. A total of 33 radioisotopes were detected. The integrated inventories were significantly less than at other sites to the east. Preliminary results of plutonium analyses are also presented, together with other deposition data in rain and soil. |
