Aliquots 2348500100025 containing 21.7 microgram 129I were dispensed on filter2348500100026 paper strips. 2348500100027 METHOD (ACTIV) 2348500100028 . Six 129I samples were irradiated for 8 min each in 2348500100029 FRM reactor pneumatic tube. 2348500100030 Three samples were irradiated in a rotating target 2348500100031 assembly for 40 min . 2348500100032 . Six 127I samples were irradiated in pneumatic tube 2348500100033 for 6 min each. 2348500100034 . PbI(2) samples were irradiated in the FR2 reactor - 2348500100035 2.98 g PbI(2) was irradiated for 25 hr without Cd, 2348500100036 2.77 g PbI(2) was irradiated for 100 hr with Cd; 2348500100037 cooling time two months; then both samples were 2348500100038 irradiated again without Cd in the graphite reflector 2348500100039 of FRM reactor for 2.5 hr . 2348500100040 . Flux monitors - Al/Au wires of 0.51 mm diameter, 2348500100041 Au content 0.1124 % . 2348500100042 . In the PbI(2) case - flux monitors were Al/Co wires 2348500100043 of 0.38 mm diameter, Co content 0.504 % . 2348500100044 . Irradiation with Cd and without Cd cover. 2348500100045 Cd cylinders - wall thickness 1mm, height 16 mm, 2348500100046 height/diameter ratio 2 - for the small 127I and 129I. 2348500100047 For PbI(2) - 43 mm long, wall thickness 0.85 mm, 2348500100048 height/diameter ratio 2.4 . 2348500100049 Neutron attenuation factors 0.963 and 0.966, 2348500100050 effective Cd cut-off energies 0.55 eV and 0.52 eV, 2348500100051 respectively. 2348500100052 (CHSEP) For PbI(2) samples.
