measuring just 4 cubic centimeters — about the size of a teaspoon of sugar — was tested at Ohio State’s Nuclear Reactor ...

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.

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

Researchers may have found a way to create a nuclear waste battery that could theoretically run for decades without needing to recharge.

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 ...

Scientists recently developed a novel battery technology that can use atomic or nuclear waste to convert electricity.

Results showed that when exposed to cesium-137, the battery produced 288 nanowatts. In contrast, exposure to cobalt-60, a more intense radiation source, yielded 1.5 microwatts – enough power to ...

The two isotopes differ in their physical attributes, with cesium having a longer half-life but lower emitted gamma radiation energy. Cobalt-60 has a shorter half-life with higher energy. Half-life is ...

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 ...
