radiation source

[‚rād·ē′ā·shən ‚sȯrs]
(nucleonics)
Usually a sealed capsule containing an artificial radioisotope, used in teletherapy, radiography, as a power source for batteries, or in various types of industrial gages; machines such as accelerators, and radioisotopic generators and natural radionuclides may also be considered as sources.

One is the supermassive black hole at the centre of our galaxy, the Milky Way, a radiation source 26,000 light years away known as Sagittarius A (SGRA).
This is because brachytherapy devices enable optimal placement of radiation source needed for high localized doses of radiation.
Brachytherapy is a highly targeted form of radiotherapy where a radiation source is placed inside or next to the area that requires treatment.
When the radiation source expires, getting a replacement source is a serious challenge, both financially and logistically.
In the study of radiation system optimization, the monitoring method of radiation environment based on wireless sensor networks (WSNs) is proposed in [1, 16-18], which improves the deficiency of fixed radiation source monitoring.
In this process, the voltage, [V.sub.wb_a], was generated in [C.sub.wb_a] and acted as a radiation source. The remaining noise current reached the fuel pump through wire harnesses propagated into the automobile body through the parasitic capacitance, [C.sub.pb_a], between the fuel pump enclosure and the automobile body.
Using proprietary miniaturized x-ray as the radiation source, the Xoft eBX System delivers isotopefree radiation treatment in a targeted prescribed dose directly to the site where cancer recurrence is most likely, designed to minimize exposure to healthy tissue such as the bladder and rectum.
The devices include a container for the medical waste and the remediation composition, a microwave radiation source, and a temperature monitoring device.
"If you take this powerful, bright radiation source in the center of the galaxy and blast the gas with its radiation, it will get excited in just the same way the neon gets excited in neon lamps, producing light," Hickox, an assistant professor in the Department of Physics and Astronomy at Dartmouth, said.
It utilizes a proprietary miniaturized x-ray as the radiation source that delivers precise treatment directly to cancerous areas while sparing healthy tissue and organs.
With GliaSite, physicians can place a specified high dose of a liquid radiation source in the areas most likely to contain cancer after brain tumour removal.
Turn them on and let them operate away from a radiation source for at least 20 minutes.
