The urinary excretion of two persons contaminated by 90Sr was followed up for 34 weeks. The excretion curve of one of these persons, whose contamination ceased 940 days before the beginning of the analyses, and which corresponds to a period of slow elimination, indicates a half‐time value of 2502 days.
