'''Radiation detectors''' provide a signal that is converted to an electric current. The device is designed so that the current provided is proportional to the characteristics of the incident radiation.

There are detectors that provide a change in substance as the signal and these may be automated to provide an electric current or quantified proportional to the amount of new substance.

{{main|Radiation astronomy/Astronomy}}
A detector in [[Radiation/Astronomy|radiation astronomy]] may need to be able to separate a collection of incoming radiation to obtain a clear set of signals for the radiation of interest. For example, a detector designed for [[red astronomy]] may need to be on the rocky-object surface of the Earth to separate X-rays and gamma-rays from red rays.

==Radiation==
{{main|Radiation/Keynote lecture}}
'''Def.''' an action or process of throwing or sending out a traveling ray in a line, beam, or stream of small cross section is called '''radiation'''.

Radiation may affect materials and devices in deleterious ways:
* By causing the materials to become radioactive (mainly by neutron activation, or in presence of high-energy gamma radiation by photodisintegration).
