在比基尼环礁，可能是在1956年和1958年核武器试验期间，一只巨大的蛤蜊壳中沉积了strontum-90的放射性物质，在从壳的横切面拍摄的放射性照片上产生了明确无误的线条。切片中看到的规则条带被解释为环形。一个环在1956年放射性层之前，两个环在1958年介入，六个环在收集时间之后，因此这只蛤蜊（长，52厘米）处于生命的第9年。
At Bikini Atoll, radioactivity from stronttum-90 deposited in the growing shell of a giant clam, presumably during the testing of nuclear weapons in 1956 and 1958, produced unmistakable lines on radioautographs made from transverse sections of the shell. The regular banding seen in the sections is interpreted as annular in nature. One annulus precedes the 1956 layer of radioactivity, two intervene in 1958, and six follow to the time of collection, so that this clam (length, 52 centimeters) was in its 9th year of life.
