2012 Dose Data from the Fixed Point Surveillance Network
The Fixed Point Surveillance (FPS) network monitors public radiation dose due to radioactive materials in the atmosphere. The FPS network is used primarily to measure the external dose from three noble gases in particular; Argon-41, Xenon-133 and Xenon-135, as well as the total combined external dose from all sources, measured as Total Air KERMA.

The system has a limit on the amount of low-level radiation it can reliably detect and use to calculate a monthly dose and the hyphens represent any data which falls below this detection limit. The minimum detectable dose for the three noble gases being monitored are:
- 6 nGy/month for Argon-41
- 3 nGy/month for Xenon-133
- 3 nGy/month for Xenon-135
These detection limits are well below the acceptable public dose limit of 1 mSv/year as published by the
