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.

But is this radiation harmful?
This application measures the WiFi electromagnetic radiation in approximation, and given the selected limits, it informs you if your environment could be considered harmful or not.
- WiFi Radiation meter
- Show the proportion of Radiation emitted by the several wireless devices around
- Create projects and save the Radiation measurements with your geo location
- Project them on Google Maps
Special thanks to Konstantinos Chalkias!
* The radiation amount is calculated by approximation of only the available wireless access points, and may be affected by the strength of your device's antenna.
The predefined gamma rate constants and attenuation coefficients were found on the web. I do not guarantee correct predefined values.
Instructions for use:
Preferences can be found by pressing the menu button. Many display options are available to customize what is on the screen.
The range on the meter can be changed in the options or by sliding your finger up or down on the screen. The left side of the screen adjusts the minimum, the right side adjusts the maximum. You can lock or unlock touch adjustments through the menu.
Custom color values can be set for the text. Sound can be enabled and customized in preferences, default is off. This will play a tone at a rate determined by the EMF reading, similar to a Geiger counter.
More detailed Instructions are available from the menu within the app.

2.Avoid high radiation after dialing in a few seconds with unique detecting technology, and you will not miss the answer;
3.Prompt you to hang up the call if you making a long telephone call,so you can reduce the Radiation;
4.Count your history of talk time to help you improve caling habits;
Simple fact: earth natural magnetic field is between 30 and 70 u Tesla (350 to 700 m Gauss). 1 u Tesla = 10 m Gauss.
Is your home EMF hazards free? You can buy a Gauss meter to measue the accurate value. However, your smart phone can also be converted as a simple Gauss meter.
This applicaiton will sound the alarm once the abnormal EMF field is detected. The screen color will also turn from health green to danger red. So scan your home now...

Some hints on comments and the EXIT function of the program. Please use the HOME button to exit the application. We didnt provide an extra EXIT button to terminate the program, as the Android System recommends not to terminate the program ourself instead let do the Android System the termination if necessary. This is to have a full compatible system and keep the OS in a stable condition. We prefere a stable system left to the user instead of doing some hacks on this -- if you really need to kill the App, use the END program function of the Android Application manager, so you dont need to reboot the Phone.
features in the last rev 1.3:
1. Backspace also can be used as the OK button, to LOAD the ship in the captains wall and to START or STOP the simulation in the main screen.
2. Buttons - User Interaction. New algorithm for handling all buttons. Now a radius region is searched, which gives a much better response. Better behavior at the border.
3. bug fix for sound not terminating when the program is exit (e.g. paused).
4. Fixed problem with the timeout message and text.
Please also write an email if you have error messages or problems.
We want to help quickly, but you need to write an email to us with details. The comment section is a bad place as we cannot reply or ask questions on the problem. We really want to help.
You can use the email button in the help menu to provide us with feedback and please use it.
The app can log counter values and the resulting statistic can be sent by email (Csv) or saved as csv or html file.
On our homepage you find a complete manual (for the FULL version) and more Infos.
