Measuring Ionising Radiation Exposure in 3 Ways
To measure radiation activity or the amount of radiation coming out of a source, Australians use the unit Becquerel (Bq) from the international system (SI) of units or the metric system.

Alpha particles’ massive size means they have very low penetration power. A piece of paper or the outside layer of the human skin can completely stop them.
A radiation incident is an unexpected event that could result in radiation exposure outside the intended range. It can result from human error, labelling issues or equipment failure, to name a few.
Bananas are tasty sources not only of potassium but radiation too! 2.5 bananas is equal to one airport security scan and 50 bananas is equal to 1 dental X-ray.
Compared to a power reactor which produces heat for electricity, a research reactor like HIFAR is solely a “neutron factory” for scientific research and the production of radioisotopes. These are essential in medical diagnosis and cancer therapy.
Some people have reported that they experience headaches, body pain, lethargy and anxiety near Wi-Fi routers and other sources of electromagnetic radiation.
At very low doses, radiation poses low risk to a person’s health. For short term, above 500 mSv is a dangerous amount but highly unlikely to be received in a short period of time.
IAEA says a monitoring programme is a “key element in verifying that a licensed radioactive waste disposal facility meets its specified performance and safety requirements.”
Did you know that X-rays were discovered by accident? It all began with physicist Wilhelm Conrad Röntgen on November 8, 1895.
With the use of radiation in different industries like medicine and nuclear power, there should be a responsible waste management plan for the safety of the community and the environment.
