High specific activity methyl-butyrate-2,3-H3 and methyl-stearate-9,lO-H3 were stored for approximately three months. The self-radiolysis decomposition products were identified by means of radio-gas chromatographic methods and the isotopic dilution technique. Rather high G-values were found for the

β¦ Synopsis
Clathrates containing high specific activity methyl stearate-9,10-H3 were stored for approximately 70 days.
The following (( host )) molecules were employed : desoxycholic acid, cycloveratryl, tri-o-thymotide and 13-cyclodextrin. The gaseous self-radiolysis products decrease significantly up to -.90 % (HT from chloeic clathrate). The total percentual decreases of the decomposition are : 16.95 % (choleic clathrate); 27.10 (tri-o-thymotide clathrate); 19.35 (cycloveratryl clathrate); 12.10 (P-cyclodextrin clathrate).
