Just what I want - millimeter wave radar blasting at me everywhere I go. Sure, it's non-ionizing radiation, but where are the long term safety studies?

- madengr 8y agoYou’ll get more radiation standing in front of a microwave oven.
- dhimes 8y agoSeriously? I thought those were pretty well shielded.
- madengr 8y agoThey are adequately shielded, but also have 1 kW resonating inside. They have enough to meet the OSHA standard of 1 mW/cm^2. The chip in question only emits 20 mW, and coupled into a 10 dB gain antenna, the EIRP is still only a few 100 mW. Now spread that over a few 1000 cm^2, and it’s not much at all. For a fun experiment, put your phone in a microwave. Notice the WiFi bars go to zero, but the cellular bars don’t change (much).

- sp332 8y ago21 CFR 1030.10 limits radiation from a microwave to 5 milliwats per square centimeter (at a distance of 2 inches). For an average-sized microwave that's over 8 watts from the front of the device. Again that's a maximum, but it's possible. TI's devices are customizable but an example on the site shows total power draw of 1.4 watts.
- sp332 8y agoSince each photon doesn't have enough power to damage your molecules, non-ionizing radiation just heats you up when it gets absorbed. Since you're not getting enough heat to cook you, or even make you slightly uncomfortable, that is the extent of the effect.
