The invention is a multi-sensor radiation detection system including a self-powered detector and an ion or fission chamber, preferably joined as a unitary structure, for removable insertion into a nuclear reactor. The detector and chamber are connecte...
An extended radiating aperture for X-rays is provided by means of a stationary target of a heavy metal positioned for uniform illumination by high speed electrons emanating from a cathode and accelerating through a difference of potential between the ...
A retractable hot center contact for a foot attachment of a photographic flash light unit having a spring biasing means mounted for movement within the attachment, a first end portion of the spring biasing means is retained against movement by the foo...
Neutron flow density distribution is determined in a nuclear reactor by a device which includes two electrodes for measuring the current flowing between such electrodes. This current, based on beta radiation, is proportional to the neutron flow densit...
A nuclear imaging system for mapping the source of high energy nuclear particles from a living organ which has selectively absorbed a radioactive compound by spatially coding the energy from the source in a Fresnel pattern on a detector and decoding t...
