| description | In standardization NAA, it is necessary to
characterize the neutron spectrum parameters such as epithermal
neutron flux shape factor (a), thermal to epithermal
neutron flux ratio (f), thermal neutron flux (uth) and epithermal
neutron flux (uepi) in the irradiation facility to
determine the concentration of an element in the sample
using absolute and k0 standardization methods. The a and
f were determined using Cd-ratio multi monitor method
using experimental data obtained in PUSPATI TRIGA
Mark II research reactor at four irradiation positions
(10, 20, 30 and 40) of the rotary rack. The calculated values
of a and f ranged from 0.006 to 0.0281 and 18.56 to 19.12
respectively. The average values of uth and uepi were found
as 2.33 9 1012 and 1.23 9 1011 n cm-2 s-1 respectively.
Moreover, a comparison of the neutron flux parameters in
the present study shows an acceptable level of consistency
with those of previous studies. |
