Bondar Clegg (lake sediment) INAA – flux 1x10**11, counting 6-11 minutes  (Au + Wt)



Bondar Clegg, lake sediment; Instrumental Neutron Activation Analysis – flux 1x10**11 (gold, weight)

General Methodology:

The weighed sample (up to 40g) is irradiated epithermally for 20 minutes in a neutron flux with an approximate density of 1x1011 neutrons/square cm/second.  Counting begins seven days after irradiation.  The counting time is somewhat variable (6 to 11 minutes) and is matrix dependent.  Counting is done on a germanium-lithium co-axial counter.  The counting data are accumulated on a VAX computer and are subsequently converted to concentrations.  Numerous international reference samples are irradiated with each batch of routine samples.
