The half‐life of two I‐125 encapsulated clinical seeds was measured with a Si(Li) semiconductor detector. Two measurements of each seed yielded an average half‐life of 59.56±0.17 days. The results are discussed in terms of the influence of possible I‐126 contamination and leakage of I‐125 activity through encapsulation. The present results are compared with a frequently cited value of 60.25±0.06 days. The difference between the two values was found to be statistically significant at a 95% confidence level.
