Abstract：
:The neon beam at 250 MeV/nucleon from the Bevalac at the Lawrence Berkeley Laboratory is bombarded in nuclear emulsion. The experimental interaction cross section of the neon beam in emulsion is 1078 +/- 35 mb, in agreement with the calculations from the modified Bradt and Peters formula. The secondary fragments were identified and their partial production cross sections were calculated. From the fluences of the primary and secondary fragments, we determine their radiation doses which are presented as a function of depth in the absorber.
