A Radiation Counter indicates the presence and intensity of radioactivity in the immediate vicinity.

Description / Specifications[edit]

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 for (and in terms of danger to) the Sophont species that created the device: most commonly this readout is preset to safe human tolerances.

Detection[edit]

The rad is a unit of absorbed radiation dose, defined as 1 rad = 0.01 Gray = 0.01 J/kg.

A radiation counter is generally set to ignore normal background radiation.

25 rads: lowest dose to cause clinically observable blood changes
200 rads: local dose for onset of erythema (reddened skin) in humans
400 rads: acute radiation syndrome in humans
1 krad: typical radiation tolerance of ordinary microchips
6 krads: typical radiotherapy dose, locally applied
10 krads: rapid fatal whole-body dose
1 Mrad: typical tolerance of radiation-hardened microchips

History & Background / Dossier[edit]

Radiation Counters are available from TL-5 onwards.

Basic models of Radiation Counter are the size of a liter bottle, while more sophisticated models are typically palm-sized. 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.

  • Battery life is around 200 hours for TL-8 (or lower) models, and several weeks for more advanced models.
  • Radiation Counters have a visual readout. More advanced models can be connected to computers for data analysis of radiation exposure.
