ARPANSA’s environmental radiation monitoring and assessment program (RADMAP-Aus) provides independent information and advice about the amount and types of radiation present in the Australian environment. The information is used to support human and environmental safety, effective regulation, emergency preparedness, education and public awareness. 

Environmental monitoring and assessment activities help us understand and measure the ways in which radiation moves through the environment (transport pathways) and identify exposure pathways for people, plants and animals. Results from measurement, monitoring and modelling inform radiation risk assessments, which are undertaken in line with the general environmental health risk assessment and risk management methodology.

The report Monitoring and Assessment of Radiation in the Australian Environment provides a framework for the development and implementation of ARPANSA’s environmental monitoring and assessment activities.

Environmental Radiation Monitoring System (ERMS)

ERMS is a network of automated ambient gamma detectors that take continuous measurements of gamma radiation. This allows ARPANSA to monitor and increase understanding of the variability of background radiation over time and to identify trends or significant changes to the radiological state of the environment.

Regulatory assurance

ARPANSA’s Radiation Health Services provide a suite of environmental monitoring and assessment services to support regulatory assurance activities.

Food and drinking water

All drinking water and food products in the human diet contain radionuclides.

Ultraviolet radiation in Australia

ARPANSA owns and maintains a network of ultraviolet radiation (UV) detectors in cities around Australia.

Radon measurements

Radon is a naturally occurring radioactive gas, which has no smell, colour or taste. It comes from the radioactive decay of radium, which is present in small amounts in rocks and soil.

Framework for Environmental Monitoring and Assessment

This publication presents a comprehensive framework for the development, implementation and communication of environmental radiation monitoring and assessment activities. The Framework provides guidance on establishing environmental programs with clear objectives driven by Community Values and expert judgement, and which consider the full lifecycle of a program during the planning process.
