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 & Radiation Levels[edit]

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

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

Rad Levels
Exposure Effect Typical Source
0.001 rads / hour No negative long term effects. Dental x-ray
0.01 rads / hour No negative long term effects. Chest x-ray
10 rads / hour Radiation sickness, nausea, eventual recovery likely. Airborne fallout as a result of a detonated thunderball device.
25 rads / hour Lowest dose to cause clinically observable blood changes.
200 rads / hour Local dose for onset of erythema (reddened skin) in humans.
400 rads / hour Acute radiation syndrome in humans.
1000 rads / hour Organ failure, death within hours.
Typical radiation tolerance of ordinary microchips.
Within the crater of a detonated thunderball device.
6 krads / hour Typical radiotherapy dose, locally applied.
10 krads / hour Rapid fatal whole-body dose, death within an hour.
400 krads / hour Rapid organ failure, death within minutes. Within the magnetosphere of a large gas giant.
1 mrads / hour Typical tolerance of radiation-hardened microchips

History & Background (Dossier)[edit]

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.

Image Repository[edit]

No information yet available.

Technological Overview of Radiation Counters[edit]

The technology is generally thought to mature within the TL:4-6 Technological Epoch.

  • Radiation Counters are available from TL-5 onwards.
