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.

The decay calculator allows the user to enter a radionuclide, reference date and reference time. The current activity is displayed and updated for radioactive decay in real time. In addition, a specified date and time can be entered and the decay corrected activity at this time will also be shown.
Users working in Nuclear Medicine departments and Radiopharmacy labs will find this decay calculator useful.
Please Note: This calculator is provided as is, without any guarantees or warranty. Although the author has tested the application and believes it to be accurate, the author is not liable for any damage or losses of any kind caused by the use or misuse of this application.

Worried about accidental exposure to radioactive material or acts of terrorism? The GammaPix App can provide timely warning of the presence of radioactivity using nothing more than your phone's camera. While it is NOT meant to be a substitute for dedicated ionizing radiation detectors, it is a rapid and convenient way of making preliminary threat estimates.
Unlike the Lite version, this app does not require a network connection to operate. We recommend you run GammaPix while connected from time to time to check for new calibrations.
This is a tool. Various circumstances may compromise the measurement or make the results inaccurate.
o Real-time mode. Watch the results as a reading is being taken.
o Three-stage mode. Quick warning of danger. A full-length reading to look for lower doses.
o Automatic monitoring for radiation when you're not using the app.
o Use either camera.
o Choice of radiation dose units.
o Faster results
We hope you enjoy using GammaPix!
Automatic monitoring will use ~1% of your battery, but could warn you of radiation even when not using the app.
A 10 to 20-minute initialization is required before you use the application for the first time. We know this step slows you down, but it really is necessary to get the best results. Please perform this step in a place you know is likely to be free of excessive radioactivity, with your device cool and unplugged.
For best results make sure no light is getting into the camera when you run the GammaPix app. Putting the phone in your pocket or covering it with a book works well.
A reading takes about 3 to 5 minutes if there's no danger. Dangerous levels will be reported sooner.
The GammaPix App will not work on some phone models because the camera optimization at low light levels gives "bright" pictures.
Not all phone models have been calibrated. We'll use your readings to provide a calibration for your model. The more you take, the sooner we'll have a calibration.

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.
The solution used for this locator app, developed by signaldisplay.com is being used in several different industries. They have uranium mining companies testing it, wireless employee tracker inside of buildings, triangulating archaeological artifacts underground, and another was tracking range animals.

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...

Advanced features include multiple reference dates, an editable database of Isotopes with their half life constants and an exportable log file to easily record activities and transfer them off your phone.
Simply long-press the reference buttons to enter reference dates then enter an activity and use Ref1, Ref2 to show the activity decayed to that reference. Use the clock button to
show the activity decayed to the current time.
An ad-supported free version is also available which has some minor limitations.

The App supports 10 different languages which can be selected when starting the game (English, French, Netherland, Norwegian, Italien, Spanish, Finish, Swedish, Daenish, Portugais and German). Any suggestions are welcome please write us.
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.
Also used in naval schools for education.
features in the last rev 1.4:
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.
