A smartphone camera can make you a walking
gamma ray detector. Without needing any extra hardware, you could get a warning
on your phone when you're approaching potentially harmful levels of gamma
radiation.
They concluded that the phones have the
processing power to detect gamma radiation with their built-in cameras and to
measure levels on the phone. With the help of a program on a remote server, the
app captures and measures an average energy level, then uses a model to figure
out what types of radioactive material could be emitting the radiation.
Basically, once your phone has been calibrated with the app, you'll have a
radiation detector in your pocket.
The scientists are considering a commercial
partnership to develop the app for the general public. In the meantime, there
are other apps that can give you an estimate of the gamma radiation around you.
Tungsten material is a suitable material
for gamma radiation protection, for more details, you could visit here.
