Abstract :
Neutron spectrum measurements using the foil activation technique have been made in two widely varying environments. One is an extremely high neutron-to-gamma field and the other extremely low. These measurements were used to characterize the fields and to evaluate the use of the DN-156 PIN diode for measuring 1 MeV equivalent neutron fluence in silicon (/spl Phi/1 MeV(Si)). The agreement between the /spl Phi/1 MeV(Si) as measured with diodes and as determined by the spectral measurements was within /spl plusmn/5%. A proton recoil neutron spectrum measurement was also made in the low gamma environment.<>
