spores : Some bacteria can form dense hardy spores,
compact and inert hibernation state.
takes more irradiation to kill a bacterial spore,
with D-values on the order of 2.8 kiloGray.
The atmosphere shields us from the sun's cancer-causing ultraviolet (UV) radiation and also moderates the earth's climate.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.

Alongside traditional methods of processing and preserving food, the technology of food irradiation is gaining more and more attention around the world. Although regarded as a new technology by some individuals, research on food irradiation dates back to the turn of the century with the first USA and British patents being issued in 1905 for the use of ionizing
