Three recent international neutron dosimetry intercomparisons are discussed: the International Neutron Dosimetry Incomparison (INDI), sponsored by the International Commission on Radiation Units and Measurements (ICRU); the European Neutron Dosimetry Intercomparison Project (ENDIP), sponsored by EURATOM; and the intercomparison carried out by the centers doing neutron radiotherapy. Physical dosimetry to an accuracy of two or three percent is desired in order to achieve a generally accepted 5 percent accuracy in dose to the tumor. In general, it is found that 3 percent accuracy has not been achieved by the intercomparison participants; however, the radiotherapy centers agree on an arbitrary (but not absolutely known) scale within this uncertainty. 10 figures, 5 tables.
