Assessment of the radiological situation resulted by the accidental release of fuel particles

“…Cl-1063 Along with data on real radionuclides fractionation in the Chernobyl fuel particles it permitted to assess the effective temperature and period of fuel annealing during the ChNPP accident [2,3]. The attempt was done and a possibility was shown to determine the localisation of the source of initial nuclear fuel release from the reactor during the ChNPP explosion [3].…”

“…Model experiments in simulated lung liquid shown that the radioactive Chernobyl aerosols on fei traces of radioactive fall-outs can be classified as insoluble ones when their inhalation intake into humai respiratory system is considered [12]. At the wide range of agrotechnical works, concentration am dispersal composition of the radioactive aerosols were measured just at the working places (cabs o tractors etc) of machine-operators considered as a critical group of population [11].…”

Multi-Element Isotopic Analysis of Hot Particles from Chornobyl

“…The 1986 accident at the Chornobyl nuclear powerplant (ChNPP) deposited a vast number of hot particles in the 30 km exclusion zone that remain there to this day [4,5]. These particles are fuel fragments originating from the reactor core, and are composed of a large variety of stable and radioactive nuclides [6,7]. They not only pose a radiological risk via inhalation [8], but will also weather and degrade over time, leaching radionuclides into the environment [7].…”

Assessment of 137Cs and 239,240Pu Distribution in Forest Soils of the Opole Anomaly

“…Estimated activities of 239 Pu and 240 Pu in the reactor core were 8.5×10 14 -9.5×10 14 Bq 239 Pu and 1.2×10 15 -1.8×10 14 Bq 240 Pu. About 1.4±0.5% of plutonium isotopes were released, mainly to the reactor surroundings (Kashparov et al 2003).…”
