| Abstract: | Following the accident at Chernobyl there was a need to determine caesium activity in individual sheep on farms. This need arose so that animals on farms within a restricted area could be released from restrictions provided the tissue caesium activity was below the recommended limit. This paper describes the development of a rapid method for the in vivo monitoring of sheep using a lead-shielded sodium iodide scintillation detector coupled to a portable single channel analyser. The method enables one sheep per minute to be monitored and the results showed a good correlation (R2 = 93%) with laboratory measurements of meat from sheep which had previously been monitored in vivo prior to sacrifice. |
