Gamma-ray emitter 85Sr added2227900100019 as a tracer of 90Sr. Sample prepared by evaporating a 2227900100020 small amount of SrCl2 solution containing 2.8 MBq of 2227900100021 90Sr and 5.4 kBq of 85Sr in a polyethylene bottle. 2227900100022 The bottle was sealed and housed in a polyethylene 2227900100023 capsule together with flux monitor wires of Co/Al and 2227900100024 Au/Al alloys. The target was irradiated in the reactor2227900100025 for 10 minutes. After irradiation, it was purified by 2227900100026 a cation exchange method. 2227900100027 METHOD (ACTIV) 2227900100028 DETECTOR (HPGE) Gamma-ray spectrum of the Sr sample measured 2227900100029 with a HPGE detector having 90% efficiency. A 5 mm 2227900100030 thick Lucite sheet was placed between the sample and 2227900100031 detector to absorb beta-rays from 90Y. In addition, 2227900100032 a 4 mm thick lead sheet was inserted to absorb low- 2227900100033 energy Bremsstrahlung. 2227900100034 DECAY-DATA (38-SR-90,29.YR) 2227900100035 HISTORY (19950910C) N.O. 2227900100036 (19961121U) + + Corrected by S.M. 2227900100037 Facility code corrected in San 001 2227900100038 names under 'Institute' interpreted + + 2227900100039 (20000503A) Corrected by S.M. 2227900100040 Reference and Subentry added 2227900100041 dates corrected 2227900100042 (20000503U) Last checking has been done. 2227900100043 (20121209A) SD: Data units were changed in Subent 003. 2227900100044 Ref. on NST,31 was added. 2227900100045 (20220215U) SD: Small corrections in all Subents.
