Contact Radioactivity Counter Customer Service

Why should I report an Issue with Radioactivity Counter?

1. AppContacter will directly Email your issue/feedback to an apps's customer service once you report an issue and with lots of issues reported, companies will definitely listen to you.
2. Pulling issues faced by users like you is a good way to draw attention of Rolf-Dieter Klein to your problem using the strength of crowds.
3. Importantly, customers can learn from other customers in case the issue is a common problem that has been solved before.

1. We tested several mobile phones at the Helmholtz research facility in Munich, using a professional radiation device in the range of 2-10 µGy/h till 1-10 Gy/h (CS137 and CO60).

2. The CMOS sensors can detect primary gamma radiation and some higher beta radiation (depends on the shieldings in the mobile phone).

3. K40 (KCL for example contains 16 Bq/g) are beta emitters with small amount of gamma (due to positron collisions)- you need also a long integration time to measure them.

4. The App is using the camera sensor to detect radiation, like a geiger mueller counter, of course with a smaller area.

5. So you need a LONG time to measure for low radiation values on this device.

6. Disclaimer: The type of radiation picked up by the camera can be dangerous/detrimental to the user's health as well as cause damage to the device. Its NOT a JOKE!

7. Feel free to use our table to assign radiation values to our counter measurements when you have the same device.

8. Important you NOISE value should be similar as in our tables, if it is too high check the tape to cover the lense - use multiple tapes if necessary and start calibration again !!!

9. If the radiation increases then also counts from the radiation adds to the CPM values (see our tables for the sensitivity).

10. This is camera noise not radiation noise basically.

11. Attention: The counts per minute (CPM) for the background noise should be low (increase the noise setting if not).

1. please update software functionality.I have Samsung Galaxy Note 9 and I needs to be a way to change it to the rear camera because the front camera keeps picking up light from the screen, for example in the notification tab gets pulled down I've tried everything for foil, duct tape foil and duct tape.

2. I have tried it with real radiation sources and it showed up.so i had a high school team test this against some of the cheaper commercial detectors and this actually held its own so for the price, i say it is well worth itDid not work, or at least very poorly on OnePlus 6T.

3. This detector works and works well! It cannot tell you what flavor the particles are but I have detected alpha and beta emissions from Granite and Gamma emissions from PET scan Glucose.

4. I used a 100 kBq (3 uCi) 241Am source directly against Al foil covered lens, without any noticable increase in count rate.I will update once i rebuy this on one of my older phones.

5. Electrical tape as well but everything still lets light inVery good radioactivity detector.

6. Radiation causes the photo sensors to "white out" resulting in fake stars.

7. It detected all! The way this works is understood well with digital Astrophotographers.

8. DOES NOT work on Android 12 :-(app works.

9. however it is glitchy and sometimes freezes or dies when switching from front to back camera.

10. I get a linear dose response from various CS-137 sources.

11. This is a clever use of what was considered a weakness in CMOS sensors.

1. Fix Radioactivity Counter Not Working/Crashes/Errors/Unresponsive & Black/White screen:

1. Restart Radioactivity Counter: Restarting the app will resolve most errors.
2. Update the Radioactivity Counter App. Here is how:
   1. On Android goto PlayStore » Search for "Radioactivity Counter" » Open Radioactivity Counter » click "Update".
   2. On iPhone, goto AppStore » Your profile » Available Updates » Check for Radioactivity Counter » click "UPDATE".
3. Clear Radioactivity Counter app cache: Clearing cached data will force your app to retrieve the latest data directly from Radioactivity Counter servers.
   1. On Android, goto Settings » Apps » Select "Radioactivity Counter" » click Storage » click "Clear Cache".
4. Check Radioactivity Counter app permissions. If any of these permissions required to use your device's features are disenabled, Radioactivity Counter might not work.
5. Uninstall and reinstall Radioactivity Counter. If nothing else has worked, completely uninstall Radioactivity Counter then reinstall.
6. Restart your device. Last, restarting your device can often clear most problems causing Radioactivity Counter not working

2. Fix Radioactivity Counter Server issues & Internet Connection

1. Check network connection: An unstable Internet will make Radioactivity Counter be unable to connect to it's servers. Ensure your wi-fi is working then restart app.
2. Disable VPN: VPN can cause connection errors and lead to Radioactivity Counter not working. Make sure all VPNs are off
3. Enable background data: When Background data is turned off, Radioactivity Counter may not be able to connect to the Internet when running in the background.
