Title: Non-destructive method for determining neutron exposure and constituent concentrations of a body

Full Record
Other Related Research

Abstract

A non-destructive method for determination of neutron exposure and constituent concentrations in an object, such as a reactor pressure vessel, is based on the observation of characteristic gamma-rays emitted by activation products in the object by using a unique continuous gamma-ray spectrometer. The spectrometer views the object through appropriate collimators to determine the absolute emission rate of these characteristic gamma-rays, thereby ascertaining the absolute activity of given activation products in the object. These data can then be used to deduce the spatial and angular dependence of neutron exposure or the spatial constituent concentrations at regions of interest within the object.

Method and an apparatus for non-invasively determining the quantity of an element in a body organ

Patent Vartsky, D; Ellis, K J; Cohn, S H

An apparatus and a method for determining in a body organ the amount of an element with the aid of a gaseous gamma ray source, where the element and the source are paired in predetermined pairs, and with the aid of at least one detector selected from the group consisting of Ge(Li) and NaI(Tl). Gamma rays are directed towards the organ, thereby resonantly scattering the gamma rays from nuclei of the element in the organ; the intensity of the gamma rays is detected by the detector; and the amount of the element in the organ is then substantially proportional tomore » « less
Apparatus for the field determination of concentration of radioactive constituents in a medium

Patent Perkins, R W; Schilk, A J; Warner, R A; ...

The instant invention is an apparatus for determining the concentration of radioactive constituents in a test sample; such as surface soils, via rapid real-time analyses, and direct readout on location utilizing a probe made up of multiple layers of detection material used in combination with an analyzer and real-time readout unit. This is accomplished by comparing the signal received from the probe, which can discriminate between types of radiation and energies with stored patterns that are based upon experimental results. This comparison can be used in the calibration of a readout display that reads out in real-time the concentrations ofmore » « less
Non-destructive determination of reactor pressure vessel neutron exposure by continuous gamma-ray spectrometry

Conference Gold, R; McElroy, W N; Kaiser, B J; ...

Neutron induced radiation damage experienced by the pressure vessel of a power reactor can be a controlling factor in defining the effective life of plant operation. As a consequence, methods of quantifying the neutron exposure fluence of reactor pressure vessels are of worldwide interest. To this end, a new nondestructive method of reactor pressure vessel neutron dosimetry is advanced. It is based on the observtion of characteristic gamma-rays emitted by activation products in the reactor pressure vessel with a unique Si(Li) Compton continuous gamma-ray spectrometer. 5 references (extended abstract).
