Abstract:
The LET distributions in front of the 80 cm-thick concrete side shield at the CERF facility were measured with a Si detector telescope (RRMD-III) covered with and without a 1 cm-thick acrylic plate. In these measurements, a slight difference between the LET distributions was seen as a result of recoil protons and/or carbon particles by neutrons. Also, the LET distributions are compared with the micro-dosimetric spectrum (i.e., lineal energy distribution) measured with a cylindrical TEPC under the same conditions.
