ARCHIVED - 2007 Dose Data from the Fixed Point Surveillance Network

The tables below show the 2007 dose data available from the FPS network.

Gentilly System - 2007

Dose Data ( nGy/month)
Station Nuclide JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
nGy (nanoGray)

A Gray (Gy) is a standard unit of measurement for radiation dose, defined as 1 Joule of energy deposited per kilogram of matter. A nanoGray (nGy) is 1×10-9 Grays and it is a much more common unit of measure for these types of very low doses.



KERMA (Kinetic Energy Released in Matter)

In this case the 'Total Air KERMA' refers to the radiation dose from all external gamma sources, not just from the three noble gases Argon-41, Xenon-133 and Xenon-135. This includes natural background radiation as well, such as from mineral deposits in the ground, radon gas in the air or cosmic radiation from space.



- (hyphen)

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 1,000,000 nGy/year as published by the  Canadian Nuclear Safety Commission in their  Radiation Protection Regulations.

nGy (nanoGray)

A Gray (Gy) is a standard unit of measurement for radiation dose, defined as 1 Joule of energy deposited per kilogram of matter. A nanoGray (nGy) is 1×10-9 Grays and it is a much more common unit of measure for these types of very low doses.



KERMA (Kinetic Energy Released in Matter)

In this case the 'Total Air KERMA' refers to the radiation dose from all external gamma sources, not just from the three noble gases Argon-41, Xenon-133 and Xenon-135. This includes natural background radiation as well, such as from mineral deposits in the ground, radon gas in the air or cosmic radiation from space.



- (hyphen)

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 1,000,000 nGy/year as published by the  Canadian Nuclear Safety Commission in their  Radiation Protection Regulations.
