Radiation detection apps don't detect a phone's various irradiations. Why?
Radiation detection apps are currently only " outwardly" focussed using the camera. It would be easy to also detect phone radiations from wifi, batteries and general phone use. Is this proof our phones are emitting controversial amounts of radiation? Can current apps discern how much background radiation is caused by phones/phone?
Cell phones put out RF (radio frequency) radiation, while radiation apps are looking for radioactive particles. If you're talking about RF radiation apps that look for signal generators, the phone isn't normally sending when it is trying to receive the signal it is trying to sense.
