Local doses associated with119mSn isomeric transition

The energy absorbed by immediate surrounding of disintegrating^119mSn nuclei have been estimated by comparing the Mössbauer emission spectra of¹¹⁹Sn in some tin compounds with the absorption spectra of the same substances after -irradiation and by simple calculations of Auger electrons energy losses. The results obtained indicate that the observed post-effects of the^119mSn decay are due to self-radiolysis and other processes, whose contributions depend on the individual properties of the matrices.
