UNCLASSIFIED NDL-TR-7 ~- A BROAD RANGE CHEMICAL DOSIMETER FOR GAMMA RADIATION. N. Klein, April 1961. UNCLASSIFIED (uv) This report describes the use of an air-saturated, aqueous benzene system as a simple chemical dosimeter that measures gamma dose in the tactical range and higher with accuracy and precision, The system described is a laboratory technique that may have field application. It is not currently suitable for consideration as a tactical dosimeter. However, this rather simple system is capable of measuring dose in the range 20 r to 35,000 r. NDL-TR-8 - NEUTRON FLUX MAPPING FOR THE KUKLA FACILITY (U). J. H. McNeilly and J. W. Kinch, September 1961. UNCLASSIFIED (uv) Neutron dosimetry measurements were conducted by this Laboratory at the KUKLA Facility of the Lawrence Radiation Laboratories, Livermore, California, during the period April 5 - 11, 1961. The measurements were made to supply input data for the Boeing Airplane Company's study of the effects of radiation on electrical components. PEE NEG Rs Hees oe St Phe el ie Tne threshold detector system was used in making the measure- ments which included (1) neutron flux versus distance from the source, and (2) perturbation of the neutron flux caused by the electrical components exposed in the radiation field. The flux shows a slight deviation from a 1/Ré dependence at distances of less than 25 cm. There is little, if any, perturbation of the flux field due to the insertion of various electrical compgnents. NDL-TR-9 - THE EFFECTS OF BORON-10 SHIELDS ON THE CALIBRATION OF NEUTRON THRESHOLD DETECTORS (u). J. H. McNeilly and J. W. Kinch, September 1961. UNCLASSIFIED (v) This report describes the results of an experiment designed to study the effect of boron-10 shields on the neutron flux and spectrum i as measured ty threshold detectors. The results include comparison of data obtained from threshold detectors exposed to a neutron field in the . following environments: in steel spheres whose periphery is filled with boron-10, in pressed and sintered boron-10 spheres, in cadmium capsules, and unshielded.
