Neutron fluence, fluence per kilowatt-hour, gamma ray exposure and gamma ray exposure rate were measured at the Harry Diamond Laboratories Diamond Ordnance Radiation Facility. The data are presented in graphical form to facilitate their use. The maximum attainable radiation exposure measured in the pulse mode is as follows in the exposure room the neutron fluence E 10 kev is 6.8 x 10 to the 13th power nsq. cm. and the gamma ray exposure is 500,000 R in the pool the neutron fluence is 5.2 x 10 to the 13th power and the gamma ray exposure 300,000R. The maximum attainable radiation exposure rate, measured at a reactor power level of 250 kw, is as follows in the exposure room the neutron fluence E 10 kev is 5.4 x 10 to the 12th power nsq. cm. sec. and the gamma ray exposure is 2,100 Rsec in the pool the neutron flux is 8.0 x 10 to the 11th power nsq cm. sec. and the gamma ray exposure is 1,300 Rsec.
