The gamma-radiation of193Au has been studied by means of a Ge(Li) semiconductor detector. In addition to the transitions observed by Svahn et. al. (Z. Physik210 (1968), 466), 21 new transitions have been found. With the use of the relative conversion line intensities from the above reference and the γ-ray intensities of this work, the number of ...

The decay of132Cs was studied by means of Ge(Li) detectors and a magnetic beta-ray spectrometer. The energies and intensities of the transitions in132Xe and132Ba were determined. Of the decay schemes proposed hitherto, that of Johnson et al. [Phys. Rev.138 (1965), B 520] was confirmed.

In the decay of 38 min63Zn γ-rays are emitted with the following energies: 0.67, 0.96, 1.44, (2.0?), 2.35, 2.55 and 2.75 MeV. There is no 0.29 MeV transition. The 0.67 and 0.96 MeV γ-rays are only strongly coincident with the annihilation radiation, not with each other. The results of the measurement are collected in Table I.

Abstract A discussion is given of the need for a simple reliable system of dosimetry, suitable for large scale use in the control of radiation processing units. The potentialities and limitations of a number of proposed systems are reviewed.

Economics of gamma radiation processing
The International Journal of Applied Radiation and Isotopes, 1959Abstract The availability, cost and utilization of γ-radiation sources are discussed. The effects on radiation processing costs of variations in these factors and in the scale of operation are considered. It is concluded that probable costs do not preclude immediate applications if plant is efficiently designed and processing is on a sufficiently ...

Shielding for Beta-gamma Radiation
Health Physics, 1993The build-up factor, B, for lead was expressed as a polynominal cubic function of the relaxation length, mu x, and incorporated in a "general beta-gamma shielding equation." A computer program was written to determine shielding thickness for polyenergetic beta-gamma sources without resorting to the conventional "add-one-HVL" method.

Abstract The gamma ray spectrum emitted in the decay of 77Br was studied with a scintillation spectrometer. Energy values and relative intensities of the various gamma rays were determined (see table 2). In addition to gamma transitions known from other studies on the decay of 77Br, three new weak gamma rays were found. These have energies of 200±10,

The development of the Gamma Knife1 was the result of Lars Leksell’s vision of an efficient and bloodless means of performing functional stereotactic neurosurgery [6]. Early efforts utilized 200 kVp x-rays, although it was recognized even then that better dose localization would be achieved with higher energy photons.
