Fact is that antlers are superb collectors of radioactive fallout. Like bones, antlers are made largely of calcium compounds, and radioactive strontium behaves chemically like calcium. Deer ingest strontium with their forage. In slowly maturing humans, only a small part of the skeleton is built each year, and therefore human bone shows an averaging of strontium over many years. But a deer's antlers are grown afresh each year, concentrating in a handy package a calcium-strontium mixture that neatly records the prevalence of strontium for that year alone...
