Nitrous oxide, carbon dioxide and ethylene were utilized as gaseous chemical dosimeters, and measurements were made of the doses absorbed by these substances in a nuclear reactor. The neutron and photon fluxes as well as their contributions to the absorbed doses were deter-mined by analyzing the data obtained from the chemical dosimetry, with particular consider-ation given to the fast neutron energy spectrum. The values of the photon, thermal neutron and fast neutron fluxes thus determined were 2.6×10<SUP>13</SUP>γ/cm<SUP>2</SUP>•sec, 3.5×10<SUP>13</SUP> n/cm<SUP>2</SUP>•sec and 7.0×10<SUP>12</SUP> exp(-<I>E</I>)sinh1/2<I>E</I> n/cm<SUP>2</SUP>•sec. These values were compared with the results from calorimetric and activation methods, and were found to be in fair agreement with each other.<BR>From the above results, it was confirmed that the above combination of chemical dosimeters are serviceable for the measurement of both absorbed dose and fluxes in a nuclear reactor.
