Corrections for real 3074000100045 coincidence summing were computed using the known 3074000100046 decay-schemes and the total counting efficiency of the 3074000100047 detector. The maximum value of this correction was 2%. 3074000100048 In most of the cases the absorption and self-absorption3074000100049 corrections were less than 7%. 3074000100050 STATUS (TABLE) Data taken from Appl.Radiat.Isot.38(1987)p.989,3074000100051 Tab.2, Goncalves 3074000100052 HISTORY (19870206C) MR- 3074000100053 (19871028U) DG.-New reference added.- 3074000100054 (20100305A) SD:Updated to new date formats,lower case. 3074000100055 Cosmetic changed, MONITOR description was corrected, 3074000100056 MONIT-REF was added.
