| Title | Licensee Reported A Sealed Acrylic Rod Source Containing Am-241 Was Unacounted For During An Inventory Made In The Spring Of 2002. |
| Event Description | The licensee reported that in the Spring of 2002 a six microcurie Am-241 source was unaccounted for during an inventory check. The item was a New England Nuclear model NES-136T sealed acrylic rod source which was purchased in 1979. It was initially thought at the time it was unaccounted for to have a half life of 433 days, therefore, being exempt from being reportable. However, during a meeting attended by the RSO last week, a discussion of AM-241 half life informed him that it is 433 years not 433 days as he had assumed in 2002 of the unaccountable source. This change in half life value made the incident reportable. |
