Automatic system for counting etched holes in thin dielectric plastics

Autor: F.J. Congel, B. G. Oltman, J.H. Roberts, Raymond Gold, Jacob Kastner, R.J. Armani, D. Dreis

Publikováno v: Nuclear Instruments and Methods. 100:247-252

Rapid determination of track densities in dielectric plastics is desirable for many experiments. A fast counting system similar to that described by Cross and Tommasino has been built for use with thin polycarbonates exposed to fission fragments. Exp

Nuclear Radiation Detection for the Natural Environment

Autor: Raymond Gold, F. Congel, B. G. Oltman, Jacob Kastner, Y. Feige

Publikováno v: IEEE Transactions on Nuclear Science. 17:144-150

Liquid scintillators, proportional counters, nuclear emulsions, etched track detectors, and thermoluminescent crystals have been used to measure the enviromental neutron flux from thermal to 10 MeV energies, below ground, at ground level, at an air-w

Production rates of neutrons in soils due to natural radioactivity

Autor: Jacob Kastner, Y. Feige, B. G. Oltman

Publikováno v: Journal of Geophysical Research. 73:3135-3142

The relative neutron yield of several targets of light elements exposed to monoenergetic ionized helium beams from the Argonne tandem accelerator was determined for alpha energies ranging from 4.8 to 8.8 Mev. Our ratio of the neutron yields for 5.3 M

Environmental neutron measurements with solid state track recorders

Autor: R. A. Parker, J. Kastner, B. G. Oltman, J.H. Roberts, F.J. Congel

Publikováno v: Radiation Effects. 3:283-285

The suitability of using 10B and 5LiF in contact with cellulose acetate butyrate (CAB) for the measurement of slow neutron densities has been investigated. The upper energy threshold of clear Diacel cellulose nitrate (CN) and of the CAB have also bee

Ecological Dosimetry: Radiation Levels Influenced by Plant Growth

Autor: Harry Moses, Jacob Kastner, James N. Beggs, B. G. Oltman, William C. Ashby

Publikováno v: Science. 155:1430-1432

The feasibility of using lithium-7-fluoride thermoluminescent dosimeters under field conditions for natural radiation at levels of 5 milliroentgens is demonstrated. Radiation dosages in tree trunks increased threefold from winter to spring and summer
