Description/Abstract:
THE VALUES FOR STRONTIUM-90 AND GROSS BETA ACTIVITY IN THE FAT AND NON -FAT FRACTIONS FROM THE LIVERS OF TWELVE COCONUT CRABS ( BIRGUS LATRO ) COLLECTED AT RONGELAP ATOLL DURING MARCH 1958 ARE PRESENTED. ALTHO UGH FAT CONSTITUTED AN AVERAGE OF 47 PER CENT BY WEIGHT ON A WET WEIGH T BASIS ( 74 PER CENT ON A DRY WEIGHT BASIS ), GROSS BETA ACTIVITY OF THE FAT FRACTION AMOUNTED TO LESS THAN 0.5 PER CENT OF THE TOTAL ACTI VITY ON A WET WEIGHT BASIS. FAT CONTENT ON A WET WEIGHT BASIS HAD A R ANGE OF 31 PER CENT TO 65 PER CENT. THERE IS A LINEAR RELATIONSHIP BE TWEEN STRONTIUM-90 ACTIVITY AND GROSS BETA ACTIVITY. SINCE THE FAT CO NTENT OF COCONUT CRAB LIVER IS VARIABLE AND THE FAT FRACTION CONTAINS PRACTICALLY NO RADIOACTIVITY, IT SUGGESTED THAT THE RADIOACTIVITY ( A ND MINERAL CONTENT ) OF LIVER SAMPLES BE COMPARED ON THE BASIS OF THE NON-FAT SOLIDS.
