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.

Gamma sterilization from cobalt-60 sources has two great virtues: simplicity and reliability. Accelerators also have advantages: the fact that only electricity is needed to power them and the ...

We're not exposed to space gamma rays here on Earth's surface ... the researchers placed their samples in irradiators powered by cobalt-60, a synthetic form of radioactive cobalt.

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 ...

In contrast, exposure to cobalt-60, a more intense radiation source ... making it safe to handle despite utilizing highly penetrating gamma radiation. The researchers observed that power output varied ...

Gamma rays are created throughout the universe in violent explosions. On Earth, they originate from the decay of radioactive elements and within particle accelerators, which are devices that smash ...

It is administered in two main ways: from outside the body using X-rays or gamma rays from radioactive cobalt; from inside the body by putting radioactive materials into the tumour, or close to it.
