摘　　要：The present study explores the potential of fission gas(Kr and Xe short life radioisotopes)released from a molten salt reactor,the separation of these noble gases using specific absorbents under well fixed conditions and the utilisation of these radioisotopes for radio-diagnostics.During operation,a molten salt reactor produces noble gas radioisotopes that bubble out from the liquid fuel and that can be sampled and treated for radiopharmaceutical applications including as tols for diagnostics using radioisotopes and/or potentially in radiotherapy for specific Vviral diseases usingβ^(-)emtters.Among them^(133)Xe is currenty used fr ung diagnostics thanks to its 132.9 keγ.The use of^(85)Kr for diagnostics is also examined.Its 514 keγcpuld be used for scintigraphy,However^(133)Xe utilisation imply also itsβ^(-)(E_(mean)≈100 kev)whose mean fre pathway of 100 nm in biological tissue or in wateris much smalier than the mean pathway of the^(95)Krβ^(-).Emphasis is placed on^(133)Xe because of its potential dual ability of imag ing and as a suggested therapeutic tool of viral lung diseases.
