Neutron energy, fluence rate, angular distributions and dose equivalent rate distributions around the thick Be, Cu, An targets bombarded by 50 MeV/u 18O-ion were measured using a threshold detector activation method. At the same time,the neutron yields of 18O-ion and the neutron emission rates in the forward direction were obtained approximately.

IMP participated in the comparison of national individual dose which was organized by National Institute forRadiological Protection, China CDC, and the comparison results were corrected and was granted with *** the comparison, RGD-3B reader, LiF(Mg,Cu,P)detectors, FJ411B annealing furnace and TLD400 detector boxwere used. The RGD-3B measuring system and LiF(Mg,Cu,P) thermoluminescence detectors were calibrated in2014. Five groups dosimeters marked number 1 to number 5 which used for routine monitor were selected to thecomparison, each group with ten detectors. The first five groups were bland samples. Group 6 was standby sampleand group 7 was for background dose monitor. The first 5 groups were exposed by the organizer in a standardflat water phantom in unknown direction with X or rays (according to ISO spectrum norm) with five differentunknown individual dose equivalent values Hp(10). The measured values were obtained according to calibrationfactors, readout values, and the corresponding background values.
