A Radiation Counter indicates presence and intensity of radioactivity in the immediate vicinity.
- It is a type of sensor.
- It may form part of a Ship Sensor Suite.
Description / Specifications
A radiation counter is used to detect radioactive emissions, most commonly beta particles and gamma rays. It can be preset to give a warning signal if levels of radioactivity rise to dangerous levels. Readouts are given in specifics and in terms of danger to the Sophont species that created the device: most commonly this readout is preset to safe human tolerances.
- It is a passive sensor.
| 25 | rad: | lowest dose to cause clinically observable blood changes |
| 200 | rad: | local dose for onset of erythema (reddened skin) in humans |
| 400 | rad: | whole body LD50 for acute radiation syndrome in humans |
| 1 | krad: | whole body LD100 for acute radiation syndrome in humans |
| 1 | krad: | typical radiation tolerance of ordinary microchips |
| 4 to 8 | krad: | typical radiotherapy dose, locally applied |
| 10 | krad: | fatal whole-body dose |
| 1 | Mrad: | typical tolerance of radiation-hardened microchips |
History & Background / Dossier
Radiation Counters are available from TL-5 onwards.
- TL-6 models are the size of a liter bottle, TL-8 models are palm sized and TL-10+ models are the size of a wristwatch or less.
- Battery life is around 200 hours for TL-8- models, and several weeks for higher TL models.
The Advanced Radiation Counter is a wrist-mounted version designed to be worn on the person or attached to the exterior of a Vacc Suit. They have a digital readout and can be connected to computers for data analysis of radiation exposure.
