Geiger counter app: measure radiation with your cell phone
Having a Geiger counter application, one naturally wonders how it’s designed to work with no corresponding sensor within the smartphone. However, it works – using the masked camera. This is how you switch your smartphone right into a simple Geiger counter. We expose you to the best apps for Android and iPhone. The Geiger counter application android cannot replace a genuine dosimeter, even though this continues to be tested. The concept behind it was to equip company smartphones by having an application such as the “radioactivity counter” and continuously appraise the radiation exposure workers are uncovered to within the relevant areas. Generally, the application Geiger counter will work – when the mobile phone is not constantly moving. Radiation entering with the camera lens opening is measured. This can be a tiny area when compared to usual dosimeter areas. Because the lens worn on our bodies is continually moving, reliable radiation measurement without additional sensors isn’t yet possible. However, that looks different should you only desire to measure your ambient radiation or even the strain on the mushrooms you’ve collected. Here the application already offers fantastic results.
This is how the Geiger counter app is applied
Before you start the Geiger counter phone application, you need to tape your camera lens – preferably the leading camera – with black tape to ensure that simply no light could get through. Next, a reasonably lengthy calibration is transported out. After about ten minutes, you are prepared to use it; however, it will take an hour or so for more precise measurements. Because to the fact that this isn’t a “fun application,” however that accurate measurements are happening, this is bearable. The Geiger counter application has access to the front and back cameras. However, the leading camera is placed in the beginning because it usually delivers more reliable values. Should you still wish to change that, this can be done using the “Menu” button under “Settings” – as you can tell, the German application is within worldwide British.
Whether something is measured following the calibration naturally depends upon the accessible radiation sources. “Radioactive material” is needed to check the part. One possibility may be the luminous numerals of wristwatches. Alternatively, you may also use an exclusion method: calibrate your ambient radiation to cover the lens area with metal throughout the measurement to avoid radiation from penetrating. You can observe in the difference the principle works. The application includes a log mode that continuously logs the measurements. To make this type of measurement, you need to either set up the smartphone inside a stable manner having a tripod or just lay it lower and approach the recorded camera lens using the sample. Mobile phone sensors can identify beta and gamma radiation, and also the application measures it in units of grey (Gy). This is the absorbed dose brought on by ionizing radiation.
Summary of the Geiger counter app “Radioactivity Counter”
The application is too complex and costly for party fun. But when you are seriously interested in calculating radioactivity having a mobile phone without special sensors, you need to come right place. Once calibrated, the radioactivity counter can appraise the radiation of various samples and – because the Nuclear Medicine Institute from the TU Dresden has determined – delivers surprisingly great results. You’ve got to be conscious that this measurement cannot help suing your landlord if you feel he’s laid shiny tiles within the bathroom. However, you can probably tell should you steer obvious from the porcini mushrooms that the friend in the Chernobyl area sent you.
