DECAY-DATA (67-HO-166-G,26.763HR,DG,80.547,0.0671) 2287100100031
SAMPLE Manganese Mn-O2 and Holmium Ho2-O3 oxide powders were 2287100100032
diluted with the finely grained Al2-O3 powder by 2287100100033
98.8 - 96.6%. Each sample was filled in polystyrene 2287100100034
cylindrical tube (height/diam = aprx 2, walls 1 mm 2287100100035
thick, internal diameter 5.0 mm) and irradiated with 2287100100036
and without cylindrical cadmium shield case 2287100100037
CORRECTION Corrections for background were made with the help of 2287100100038
irradiating a bare cadmium case, for self-shielding - 2287100100039
