Cobalt-60 is a radioactive material that emits lethal gamma radiation. Used in industry, medicine, and even theoretical doomsday weapons, how dangerous is this silent threat? Find out now!

Scientists use light-emitting crystals and solar panels to turn the latent energy in nuclear waste into microbatteries.

The team tested the battery prototype with cesium-137 and cobalt-60, common radioactive byproducts of nuclear reactors. Using cesium-137, the battery produced 288 nanowatts of power, while cobalt-60 ...

The source was a discarded medical device containing Cobalt-60, a highly radioactive substance. How did the radioactive ...

Dr. Raymond Cao. The prototype, which measures about 4 cubic centimeters, was tested using two radioactive isotopes: cesium-137 and cobalt-60. These isotopes are significant fission byproducts from ...

This tiny Cesium-137 source is far less radioactive than the Cobalt-60 sources this message usually applies to. However, it’s still radioactive enough that you don’t want to be anywhere near it.

Bits of stainless steel containing radioactive cobalt-60 were found on maintenance workers as they left the building through a recently installed portal monitor system. Because that system was not yet ...
