What is the Story Behind the Radiation Symbol?
The trefoil – a three-bladed radiation warning symbol – wasn’t originally black and yellow. In 1948 it was considered for wider use but its first print was a magenta symbol on a blue background.
The Future of Space Exploration: Protecting Astronauts from Cosmic Radiation
According to a 2020 study, the radiation exposure on the Moon is 2.6 times higher than on board the ISS. While on Mars, astronauts would be exposed 40 to 50 times the average on Earth.
Sealing, Ventilation and Other Ways to Reduce Home Radon Levels
Because radon is invisible and odourless, the only to know your radon exposure is to test for it. There are DIY kits in hardware stores or online but you can hire a professional tester for it.
How Are Radioactive Materials Transported?
Every year, millions of radioactive materials are transported worldwide — radiopharmaceuticals, radioisotopes for agriculture and radioactive substances for nuclear fuel production.
Contributions of Women to Radiation Science
Aside from Marie Curie, many other women pursued a career in science and contributed to our modern understanding of radiation. Let’s take a look at their profiles.
Achieving ALARA: Environmental Monitoring for Radiation Protection
Measuring external radiation fields ensures that radiation levels are as low as reasonably achievable (ALARA) in the community, especially in areas where radioactivity from industrial activities makes an impact.
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.
An Intro to Alpha, Beta and Gamma Radiation
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.
Submit, Review and Share: Reporting Radiation Incidents for Safety
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.
Five Sources of Radiation You Didn’t Know
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.
