Editing Dosimeter (section)

====Quartz fiber dosimeter====
 {{Main|Quartz fiber dosimeter}}
These use the property of a quartz fiber to measure the static electricity held on the fiber. Before use by the wearer a dosimeter is charged to a high voltage, causing the fiber to deflect due to electrostatic repulsion. As the gas in the dosimeter chamber becomes [[Ionization|ionized]] by radiation the charge leaks away, causing the fiber to straighten and thereby indicate the amount of dose received against a graduated scale, which is viewed by a small in-built microscope.<ref name="Frame">{{cite web

They are only used for short durations, such as a day or a shift, as they can suffer from charge leakage, which gives a false high reading.
However they are immune to EMP so were used during the Cold War as a failsafe method of determining radiation exposure.

They are now largely superseded by electronic personal dosimeters for short term monitoring.
