R. Agar et al., DETERMINATION OF TOTAL BETA-ACTIVITY IN SHEEP BONES OF DIFFERENT AGESIN TURKEY AFTER CHERNOBYL NUCLEAR-REACTOR ACCIDENT, Revue Roumaine de Chimie, 39(4), 1994, pp. 365-371
In this study, the total beta-activities in the front leg bones of she
ep originated from different regions of Turkey and at various ages wer
e determined. In addition, the relationship between Sr-90 and total be
ta-activity in the same bone-ash was investigated. It was shown that t
he total beta-activity strongly depends on the age of the sheep as wel
l as on its origin. The beta-activity level is maximum at one year old
and decreases rapidly with age. After the 3rd or 4th year it reaches
almost a constant value.
