Five Consumer Products That Contain Radiation
Wonder why many exit signs light up even when the power is out? That’s because these contain tritium, a naturally-occurring radioactive isotope of hydrogen.
From the Ground Up: Radiation Exposure in Borehole Logging
With borehole logging devices containing sealed radioactive sources, exploration workers can be exposed to significant radiological health hazards.
The World’s Most Radioactive Places
In the 1940s, nuclear weapons production began at Hanford which generated large amounts of radioactive and chemical wastes, both solid and liquid waste. It’s one of the largest and most expensive cleanup projects in the world.
Where Do Electromagnetic Fields Come From?
The discovery of electromagnetism was a lucky accident. Before it happened, scientists thought that electricity and magnetism weren’t related.
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.
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.
Protecting The Community: How Do We Manage Radioactive Waste?
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.
Working with the Invisible Radiation: 5 Radioactive Careers
All careers that work with and around radiation sources are very careful. There are regulations on dose limits and radiation workers strictly follow them.
Radiation in High Altitudes: Do Flight Attendants Need Radiation Monitors?
The higher you fly, the higher the level of radiation. That is why pilots and flight attendants are classified as radiation workers.
