Description
The calculation of detailed radioisotopic composition in biological shield and verification with experimental results is presented. Neutron fluxes in different spatial locations in biological shield are obtained with TORT code. Libraries used with TORT code are BUGLE-96 (coupled 47 neutron groups and 20 gamma groups) and library derived from VITAMIN-B6 (coupled library with 199 neutron groups and 42 gamma groups). Isotopic composition is calculated for various irradiation intervals and also for several decay intervals from different initial irradiation intervals. Neutron fluxes obtained with TORT code are used as input for activation calculation in several locations of the biological shield. Several neutron spectrum constants from known neutron flux have to be derived before isotopic calculation. SCALE code package is used for isotopic calculation. Experimental results used for comparison are available from irradiation experiment with selected type of concrete and other materials in beam port 4 (irradiation channel 4) in TRIGA Mark II reactor. These experimental results are used for verifying the calculation models. The agreement between the measured and calculated activities is within the interval of experimental error.(author)
