Bondar Clegg (stream sediment) NADNC(U)
Bondar Clegg, stream sediment; neutron activation-delayed neutron counting (uranium)
Uranium was determined using a neutron activation method with delayed neutron counting. With the exception of the irradiation facility, the method is very similar to that used by AECL in previous years, a detailed description of which is provided by Boulanger et al. (1975). A two gram sample was irradiated for 10 seconds. The operating flux was 10 x 10** 13 neutrons/sq cm/sec. After a 10 second delay, the sample was counted for 10 seconds. The counting equipment was of AECL design. Calibration was done twice a day or as required. One standard was analysed after every 20 samples. Detection limit = 0.5 ppm.
