Original Post

I was curious what the more affluent “scientific members” of this site felt about radiation heating solutions compared to convectional? Yes, I’m aware that the sun is radiation and is DC (thus the cause of external skin cancer). Then we have instances of AC radiation like microwaves that penetrate beneath the exterior and cause molecular friction to induce heat and can agitate mutated cells in people susceptible to certain forms of internal cancer.

Do you feel it’s best for the family to use pure convectional heating that depletes the oxygen around you but warms the air, reflective *radiant* convectional heating to burn the oxygen and focus the radiation, or the popular radiant heating with uranium quartz and a reflector that warms whatever is within it’s path from the inside out?

Besides folks with a pace-maker that should avoid radiant heat, I hear that even man-made radiant heat in general is terrible for the human heart and can cause heat stroke for the human brain that’s meant to operate at only a few degrees Fahrenheit less than the ideal 98.6. Heck, It’s generally advised to avoid infrared saunas on a regular basis (and what’s more regular than the heater in your own home?)

Since Microwave ovens only still exist due to greedy lobbyists (In 1979 they were banned in the Soviet Union for obvious reasons), is it wise to put our bodies under the same stress for the economic reasons of our heating bill as well?

All heat is a form of radiation, but do we want it to warm us naturally from the outside in, or cook us from the inside out? I’m reluctant and confused about my next heating purchase.

While convection heating is safe overall, is it that much worse to radiate a convectional source? I see plenty of radiant reflectors using metal coils or ceramic PTC sources, they surely can’t be as bad for you as Quartz reflectors, right?

I’m stumped, and look forward to all educated responses.

You are confused on a few things.

Heat causes heat stroke. It doesn’t matter if it came from conduction, convection, or radiation.

Radiation is merely the expression of electrons from a ponderable mass. If you hold your hand over a candle you are feeling radiant heat. If you hold your hand over a light bulb you are feeling radiant heat. If you hold your hand over a heating coil you are feeling radiant heat.

Infrared radiation isn’t going to kill you, either… Just about everything in the universe radiates infrared radiation if it is at room temperature. You must be thinking of ultraviolet, which is on the opposite end of the visible spectrum.

Microwave ovens are pefectly safe. ??? You know that curious screen you see built into the door of your microwave? That’s a variant of a Farraday cage. The wavelength of microwave radiation is too high to fit through the gaps in the cage so it is reflected back into your food. You could staple your nutsack to the top of the microwave and cook a Thanksgiving turkey in it for an hour and not even a single chromosome would notice. It’d still hurt, though.

You simply will not find a heater on the market which warms you from the inside out.

I have replaced all of the portable heaters in my home and office with Infrared Quartz Tube heaters, and I am a (former) fluid dynamics engineer.

This makes me curious. I remember hearing stories from people who were supposedly told by doctors that they could have gotten cancer as a result of a radiation leak from their microwaves.

Is there any validity to such assertions? If a microwave can leak a harmful radiation, how would one know that it is doing this?

Even if your microwave oven is leaking, it’s only leaking EM radiation, not ionizing radiation. It’s basically the same energy your Wifi and bluetooth devices put out, just a lot more of it. It’s also being bounced around inside a Faraday cage, which is neither here nor there…

BTW, the principle of the MWO (dielectric heating) was discovered when an engineer walked in front of an experimental radar dish (!) with a chocolate bar in his pocket. Notice, he observed afterward that the candy-bar had been heated, not that he had been heated. He was also probably exposed to a much higher “dose” than a leaking MWO can put out. Obviously, he also lived long enough to tell others about his discovery 😛

Here is a schematic for a leak detector. Unlike the one MineStorm posted, it includes a battery-powered amplifier. Whether that makes a difference as to its effectiveness, I couldn’t say…
