Subversive reason for ionizing foods.
The food industry does not ionize foods to protect you from germs. It does so to prolong shelf life.

Disagree with unlabeled irradiation of food.
I disagree that it is good to irradiate food without the consumers' knowledge. I agree that it can kill germs, and I agree that the food is not radioactive. However, ionizing radiation is radiation that ionizes the atoms in the food. An ionized atom or molecule can be missing an electron deep in the atom. The chemistry of an atom or molecule depends only on its outermost electrons, and so ionized atoms or molecules enjoy the same chemistry in the body as unionized ones. However, ionized atoms or molecules have a different electric charge on them, causing abnormal behaviours with respect to other atoms and molecules. (This is the danger of ionized atoms and molecules in one's body and what causes radiation sickness if the level becomes very high. Lower levels have been proven to cause various health problems including cancer) My point is that I do not want to eat food with ionized atoms or molecules, because we know that we are what we eat. It is true that we cannot help receiving ionizing radiation everyday, and our bodies can handle certain amounts, but I want a warning if the food I am purchasing has been artificially ionized so I can choose not to buy it. I have nothing against irradiating food if someone wants such a thing and they choose to buy it labeled as such. Supposedly there now exists no law to label ionized food. Please tell your grocer that you want to know which foods have been artificially ionized. Thank you.

Ion irradiation induced hollow and sandwiched...
We report on the fabrication of hollow and sandwiched nanoparticles by ion irradiation. Ag nanoparticles embedded in silica were irradiated by N, Si, Ar, and Cu ions at 300 keV to a fluence of 5 x 10 ions/cm, by Cu ions at varying ...... Read more...

July 8, 2003 -- Irradiated meat is pretty dar...
Supermarket flyers claim irradiation kills any germs that might lurk in food. They also claim you can't taste the difference between irradiated and non-irradiated meat. Neither claim is true, according to a report in the August issue of ...... Read more...

The Bogus $1 Million Meat Prize - Slate
An outbreak of E. coli isn't usually the stuff of feel-good stories. Feel-bad is more like it—or even feel-organ-failure. But recent E. coli outbreaks can offer us a bit of solace. We live in the anxious age of synthetic biology, when scientists ...... Read more...

Light and Infrared irradiation in CCTV system...
Over the past few years we have witnessed the appearance of day night CCTV cameras, all featuring a “miraculous” capability to amplify by many hundred folds the camera “minimum illumination” by removal of the IR cut filter and by turning off the color circuit. Usually, the day mode sensitivity ranges from 1 lux to 0.25 lux and leaps to 0.01 ~ 0.0001 lux for the camera’s night (B/W) mode. This “miraculous” increase is not real; it is a measurement trick by exposing the CCD (Charged Coupled Device) to high power infrared emission and specifying it inadequately in a very low lux value....

Irradiation Wikipedia RSS Feed
Irradiation is the process by which an item is exposed to radiation. The exposure can be intentional, sometimes to serve a specific purpose, or it can be accidental. In common usage the term refers specifically to ionizing radiation, and to a level of radiation that will serve that specific purpose, rather than radiation exposure to normal levels of background radiation or abnormal leves of radiation due to accidental exposure.
Most forms of radiation do not induce a state of radioactivity in the target. Examples of this include gamma rays, electron beams or X-rays if employed at or below the energy levels permited by national and international regulatory agencies for industrial applications. Gamma rays and X-rays are very-short-wavelength electromagnetic radiation consisting of photons that penetrate through solid matter until they scatter electrons from molecules by means of the compton effect or at lower levels the photoelectric effect. These electrons then induce the desired effects in the material, by destroying pathogen DNA or improving material characteristics. Electron beam irradiation employs electrons, but has a much lower power of penetration.
If administered at appropriate levels, all of these forms of radiation can be used to sterilize objects, a technique used in the production of medical instruments and disposables, such as syringes as well as in the disinfestation and sterilization of food. Irradiation can further more be used in cross-polymerization of plastics or to improve material qualities of semi-precious stones. Irradiation is also employed to prevent sprouting of certain cereals, onions, potatoes and garlic. During the 2001 anthrax attacks, the US Postal Service irradiated mail to protect members of the US government and other possible targets. This can be of some concern to people, including artists; according to the ART in Embassies programme "incoming mail is irradiated, and the process destroys slides, transparencies and disks."1
