Radioactivity-Meter APPLICATION description
Radioactivity-Meter uses the smartphone to meter the ambient radioactivity.
Use your smartphone as a Geiger counter to measure the radioactive radiation in your environment. The app uses the noise induced by the radioactive radiation in the smartphone's hardware to detect and quantify the radioactivity.
The most important part for the detection of the radioactivity is the camera chip of the smartphone. During the measument absolutely no incident light is allowed for the camera. Therefore the camera lens must be sealed e.g. by a black insulating tape. Of course you can keep the lens shut by your finger, but sometimes a little light shines through the fingers. In this case use at least additionally a cloth to shut the lens.
First calibrate the radioactivity-meter for your smartphone-hardware:
a) Fix the zero point where no radioactivity is caught by the smartphone. The zero point must be fixed at the lowest temperature of all future measurements.
b) Measure the radioactivity at a place, where the current radioactivity is known and assign this known gauge value and its unit to the value, measured by your smartphone to establish a relation between the internal hardware-dependent values of the smartphone and the real absolute quantity of radioactivity. The more exact the calibration and the higher the gauge value, the better the measurement results. From then on your radioactivity-meter is able to indicate the current radioactivity.
Due to the different hardware of the various smartphones we cannot ensure, that Radioactivity-Meter works on all smartphones with sufficient accuracy.
Since Radioactivity-Meter uses statistical algorithms to calculate the stochastic noise processes, the measuring situations should be always as similar as possible to avoid deviations of the metered values: same ambient temperature (without the zero point fixing), same up time of the smartphone, same method for sealing the camera lens etc. For this reason only single measurements are possible, no continuous measurements.
That way you can use your smartphone to determine at least the tendency for the changes of the radioactivity radiation.
