Aquilina,L., Matray,J.M. and Lancelot,J.(2012): 25 years after the Chernobyl power plant explosion: Management of nuclear wastes and radionuclide transfer in the environment. Applied Geochemistry, 27, 1291-1296.


wThe year 2011 was the celebration of the 25th anniversary of the Chernobyl nuclear accident (26 April, 1986). The explosion of nuclear reactor no.4 from the RBMK nuclear power plant (Fig. 1) was the worst industrial nuclear accident and resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment (Anspaugh et al., 1988; MacKenzie, 2000). Revised estimates of the principal radionuclides released during the course of the Chernobyl accident (decay corrected to 26 April 1986) indicate that a total amount of almost 13,650 PBq (Peta Bq equivalent to 1015 Bq) was released during the course of the Chernobyl accident (I.A.E.A., 2006) including 6533 PBq of rare gases (mostly of 133Xe), 4260 PBq of I (1760 PBq of 131I), 168 PBq of Cs (85 PBq of 137Cs) and 1400 PBq of Te (129mTe and 132Te).
