Albedo thermoluminescent and direct-reading electron personal neutron dosimeters were examined. The ratio introduced by the difference between calibration and operational spectra were studied. The ratio of dosimeter reading and personal dose equivalent to a variety of workplace spectra after calibration is in the range from 0.6 up to 106. A new dosimeter for neutron exposure was presented. It is suggested that the dosimeter should be used inside of the body. The difference between its response function and fluence-to-effective dose conversion function is in the factor of 7 and 9 for anteroposterior (AP) and rotation (ROT) exposure geometries respectively. This dosimeter might be used at emergency situations, when neutron spectrum is similar to one of nuclear fuel radionuclides fission reaction.
