Territory contamination with the radionuclides representing the fuel component of Chernobyl fallout

On the activity ratio90Sr/137Cs in soil of the Chernobyl Nuclear Power Plant 30-km zone in Ukraine

“…However, it is necessary to be sure of the correctness of assessments in works [1,2]. The basic purpose of the present study is to check the correctness of the estimation of 90 Sr content Q( 90 Sr) from 137 Cs content Q( 137 Cs) in the soil of the 30-km zone of the ChNPP in Ukraine in [1,2] and emergency release of the nuclear fuel and transuranium isotopes as well.…”

“…If fallouts of plutonium isotopes, as it follows from the works [1,2], are twice less than the commonly accepted value, then the long-term forecast of α-emitting isotopes of transuranium elements should also be more favourable. However, it is necessary to be sure of the correctness of assessments in works [1,2].…”

“…In the past years the attention is again drawn to the problem that was probably solved a long time ago in the works by Kashparov and his research assistants [1,2] and in other papers of this group -to the estimation of fuel release during the Chernobyl Nuclear Power Plant (ChNPP) accident.…”

“…Instead of the commonly accepted (3%) value of nuclear fuel release (outside the ChNPP site [3]), in [1,2] on the basis of estimation of 90 Sr content Q( 90 Sr) in the 30-km zone by 137 Cs content Q( 137 Cs), the fuel release value of 1.5% is proposed to the Ukrainian 30-km zone of ChNPP. According to opinion of the authors of [4], the emission of plutonium isotopes should be reconsidered and its value reduced as well.…”
