Mostrador real de radiactividad basado en un sensor de la cámara, sin de hardware adicional.
Se trata de utilizar el sensor de la cámara para detectar la radiación, como un Geiger Müller.
Medimos algunos teléfonos móviles en el centro de investigación de Helmholtz en Munich.
En nuestra página de inicio usted encuentra algunos resultados para dispositivos diferentes que ya evaluamos.

Radioactivity Counter

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.

This is a real working radioactivity counter. You only need a BLACK TAPE to cover the lenses !!
Its NOT a JOKE! The App is using the camera sensor to detect radiation, like a geiger mueller counter, of course with a smaller area. 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). The CMOS sensors can detect primary gamma radiation and some higher beta radiation (depends on the shieldings in the mobile phone). See FAQ on our homepage for what you can measure and how.
PLEASE SEND US FEEDBACK via EMAIL !! We add new devices in short intervals.

Attention: the tape must shield the light completely. Please check with a light source ! The counts should not increase.
On our homepage you find several measurement result for different devices we tested so far. Some are excellent, some not that sensitive.
Feel free to use our table to assign radiation values to our counter measurements when you have the same device.
The real values might differ as sensors can change. There we need your help and the help of the manufactures for a future calibration service.
You can use the contact 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. Help supporting this idea by buying the App please.

If you need any help, PLEASE send us an email. We have difficulty to answer the comment section below, so please ask us first on measurment problems. We help as fast as possible. Please contact us on any problems you have with this application. Look at our videos, more are comming soon. Attention: The counts per minute (CPM) for the background noise should be low (increase the noise setting if not). This is camera noise not radiation noise basically. If the radiation increases then also counts from the radiation adds to the CPM values (see our tables for the sensitivity). If you have a phone with 200 CPM for 100 uGy/h then the background noise produces for 100 nGy/h only 0.1 CPM. That means in 10 minutes ONE counts in 100 minute TEN counts adding to the CPM0 (noise of sensor). So you need a LONG time to measure for low radiation values on this device. Attention: AM241 (smoke detectors) only emit ALPHA rays, they get stuck in the plastic of the phones. H3 (tritium - watches etc) are beta emitters with 45 keV. They also get stuck quickly, mainly already in the watches.
Good objects are TH lenses (up to 30% TH232), pitchblend (gamma of decay products) and CS137 for checking food which might be contaminated (if larger 1 uSv/h).

* saving raw counter values in 3 different noise levels
* saving temperature data
* saving location (optional)
* saving settings data
* export by email (CSV) or file, CSV / HTML
* export of mean values in Counts + standarddeviation
* unit converter (Sievert, Gray, Rem...)

We just released a comprehensive help on our homepage -- Please before writting a bad one star comment write us we will help you very quickly PLEASE !!!
