Microwave Fears

“Something else my dad told me was that when you heat up food in the microwave, you can’t stand in front of it or you’ll get cancer. But I used to really like processed food, so I would always use the microwave and I would be really hungry so I’d stand in front of it and wait and he would get mad.”

The health belief that microwave radiation will induce cancer is something that I’ve heard before. I have also heard this belief applied to the tera-hertz radiation used in TSA body scanners. Many of my relatives from Taiwan have also mentioned this health belief about radiation in general.

As mankind has entered the nuclear era, harnessing the intramolecular forces for energy and weaponry, radiation has become a very real threat. Radiation often dominates our news and our history. Chernobyl, Fukushima, Three Mile Island, and Hiroshima have left very strong impressions on the global consciousness. This fear is perhaps intensified by the fact that radiation is an invisible force that none of us are capable of perceiving. We do not know when we are subjected to it and most of us do not understand the complexities of its various forms. So we’ve simply learned to fear the word “radiation”, associating it with all of the nuclear tragedies that has befallen mankind.

However, this fear of microwave radiation and tera-hertz radiation is unfounded. Microwave radiation and tera-hertz radiation are very different from the radiation that nuclear meltdowns produce. I once held the belief that microwaves could induce cancer. A physicist I worked with in high school told me that while high concentrations of microwave radiation might cook a human being from inside out, microwave radiation simple does not carry enough energy to do the genetic damage to induce cancer. The same applies to tera-hertz radiation.
