Radon monitor

The radon monitor comprises of a Polyallyl Diglycol Carbonate (PADC) plaque loaded inside a holder prior to delivery to measure possible average radon concentration.

These are passive detectors which means you will not see a value displayed in real-time, a report will be provided upon return of the monitor to ARPANSA.

Who is the Radon monitor for?

The Radon monitor is suited for workers in the following occupations who may need to be monitored:

• mining
• underground work activities.

These monitors can be ordered by employers to use as an area monitor or a wearable monitor for workers.

If you wish to measure the indoor radon concentration from within your home, you can hire a personal-use radon meter found in our hire of radiation meters section.

How long is the monitoring cycle?

The monitoring cycle is 3-12 months.*

How much does it cost?

The cost of the monitor is $37.40 inc GST.

How is it worn?

The monitor is worn at chest or waist level.

How is an area monitored?

The monitor is placed in the selected room approximately 1 to 1.5 metres above the floor.

What does it measure?

The Radon monitor measures the amount of radon in enclosed spaces.

Monitor usage

Radon is a radioactive gas that builds up in closed spaces, especially in underground workplaces. Increased exposure to radon is associated with an increased risk of developing lung cancer. Our radon monitor comprises of a PADC plastic plaque enclosed inside a holder to measure average radon concentration. It uses the same technology as the neutron monitor, although the holder is different. It can be used as an area monitor or worn like a personal monitor. A cycle period of up to 12 months is offered.

Detailed costing

*A minimum monitoring period of 3 months to a maximum of 12 months is required to ensure a statistically reliable estimate of the radon concentration.

Each delivery of radon monitors will include a control monitor free of charge.
