Like ultraviolet radiation and X-rays, gamma rays can kill microorganisms and are used to sterilize food and other objects, such as medical instruments and equipment. Gamma radiation is also a ...

When you think of a radiation detector, you’re probably thinking of a Geiger tube and its high voltage circuitry. That isn’t the only way to measure gamma radiation, though, and [Alan] has a ...

Radiometric or gamma level/density instruments are most often used ... the source holder must have a lockable shutter mechanism to block the radiation, or a mechanism to rotate the source away from ...

Researchers have decoded the chemical mechanism behind the extraordinary ... proteins in vaccines that require sterilization ...

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 ...

The thicker the substance, the more the radiation is absorbed. Alpha, beta and gamma radiations penetrate materials in different ways. Alpha radiation is the least penetrating. It can be stopped ...

The condom will reduce the risk of contamination, but will not shield from the I-131 gamma radiation. In most cases ... which localizes by a mechanism similar to that for strontium-89, i.e.

Radiation treatments may offer a means of reducing this problem of penetration, especially in large built-in timbers, such as oak infested by the death-watch beetle, but before their possible ...

The positioning and the intensity of the gamma ray sources are carefully calculated to ensure that the cancer cells receive enough radiation to kill them whilst the surrounding tissue remains in a ...

The origin of highest-energy gamma radiation in the nearby radio galaxy Centaurus A could now be localised for the first time ...
