Several occupations bring workers into contact with radioactive material on a daily basis, for example: X-ray technicians, nuclear power plant workers and doctors using radiotherapy. The technology associated with calculating radiation exposure in human tissue or inanimate objects is called Dosimetry.

Radiation detector are the devices that measure these types of doses, through sources such as X-rays, Alpha as well as Experiment with particles as well as Gamma rays. A Geiger counter as well as radiation dosimeter are two regular devices that have different methods of detecting radiation.

The radiation dosimeter could calculate the quantity of radiation absorbed over time not to mention alert of harmful levels. A typical version is the dosimeter logo which has a strip which changes color to indicate higher doses.

The quartz fiber and thermoluminescent dosimeters are more sophisticated devices that accurately keep track of much smaller amounts of radioactivity. An electric charged gas is contained within the quartz fiber detector. Because radiation ionizes the gas, the charge is actually reduced causing a hook to rise. The thermoluminescent dosimeter measures the noticeable light that a heated crystal emits, with radiation affecting the quantity of light released.

The Geiger counter also runs on the gas to calculate ionized contaminants within the surrounding environment, however, it typically only detects levels of radiation at a given moment, rather than an accumulation over a period of time.

Those who are not at risk are buying detectors as new risks are discovered. A rise in sales of Dosimeters and Geiger counters occurred because of the escape associated with radioactive gases during a nuclear reactor turmoil in Asia.
