Abstract:

The Operation Teapot program for the correlation of prompt- neutron and prompt-gamma radiation dose with biologic effects includes 1 Prompt- neutron and prompt-gamma angular distribution measurements as a function of distance. 2 prompt-neutron spectra measurements. 3 the determination of neutron and gamma attenuation coefficients for structural and other shielding materials, including terrain. 4 correlation of radiation dose measurements with effects in several species of animals. 5 gamma air-phase propagation measurements. 6 gamma and neutron depth-dose measurements. To accomplish these objectives two dosimeter technics were used. One the water-equivalent, single- phase dosimeter is sensitive to fast neutrons and gamma rays. The other the 2-phase, fast neutron insensitive gamma-ray dosimeter is less than one percent sensitive to fast neutrons but responds to gamma radiation. Both systems are sensitive to thermal neutrons but can be shielded with lithium to reduce this response. These two systems were used primarily for gamma measurements.
