Uptake of strontium-90 by various tissues of male Lcbistcs versus days in water containing 9 X 104 counts per minute per milliliter. Values for each tissue represent rate of up- take of strontium-90 in terms of counts per minute per 100 milligrams per day. Each point represents 6 values. and viscera accumulate significantly more strontium-90 than calcium-45 on a con- centration basis. Muscle tissue, on the other hand, tends to incorporate somewhat less strontium-90 than calcium-45. A comparison of the total distribution of stron- tium-90 and calcium-45 in the various tissues of the body following 10 days of up- take of the isotope from water (Table III) is consistent with the data based on TABLE II Relative uptake of strontium-90 and calcium-45 by tissues of male Lebistes Tissue Strontium-90* Calcium-45* "t" "P" Carcass ± ** (16)*** ± ** (20) — — Head ± (18) ± (19) < Viscera ± (18) ± (21) < Muscle ± (17) ± (20) < Spine ± (15) ± (16) < The values represent the ratio cpm/100 ing. tissue cpm/100 mg. carcass the water activity varied from 104 to 106 cpm/ml. for each isotope. * Standard error. * The numbers in parentheses indicate number of fish analyzed. derived from 3 to 5 experiments in which Students "t" value = Mi - M2 / sth2 + sd22 y \Ni + X, - 27 [7 NtN2 V] L\ Ni + No 7 J '.
