Results are given on the half-life T of berkelium-249 derived from observations on the activities of 30 radiometric preparations made over periods of up to 1181 days (about 3.6 T). The result is 330 + or - 4 days for 0.95 probability and agrees within 0.3% with the previous value of 329 + or - 4 days derived from observations on the same specimens for shorter periods up to about 600 days (about 1.83 T). This indicates that the previous result is reliable and that the radiometric determinations are correct, as well as that the radiochemical purity of the berkelium-249 specimens was high.
