Top 5 Apps Similar to Mobile Network Radiation
Radioactivity Counter 2.1
Radioactivity Counter This is a real workingradioactivitycounter.You only need a BLACK TAPE to cover the lenses!!Disclaimer: Thetype of radiation picked up by the cameracanbedangerous/detrimental to the user's health as well ascausedamageto the device. Its NOT a JOKE! The App is using thecamerasensorto detect radiation, like a geiger mueller counter, ofcoursewitha smaller area. We tested several mobile phones attheHelmholtzresearch facility in Munich, using aprofessionalradiation devicein the range of 2-10 µGy/h till 1-10Gy/h (CS137and CO60). TheCMOS sensors can detect primary gammaradiation andsome higherbeta radiation (depends on the shieldingsin the mobilephone).Typically not going into saturation as most GMtubes. SeeFAQ onour homepage for what you can measure and how.PLEASE SENDUSFEEDBACK via EMAIL !! We add new devices inshortintervals.Attention: the tape must shield the lightcompletely.Please checkwith a light source ! On our homepage youfind severalmeasurementresult for different devices we tested sofar. Some areexcellent,some not that sensitive. Feel free to useour table toassignradiation values to our counter measurements whenyou havethe samedevice. The real values might differ as sensors canchange.Therewe need your help and the help of the manufactures forafuturecalibration service. You can use the contact button inthehelpmenu to provide us with feedback and please use it. If youneedanyhelp, PLEASE send us an email. We have cannot answerthecommentsection below, so please ask us first onmeasurmentproblems. Wehelp as fast as possible. Please contact uson anyproblems youhave with this application! Look at our videos,moreare commingsoon. Attention: The counts per minute (CPM) forthebackgroundnoise should be low (increase the noise setting ifnot).This iscamera noise not radiation noise basically. Iftheradiationincreases then also counts from the radiation adds totheCPMvalues (see our tables for the sensitivity). If you haveaphonewith 200 CPM for 100 uGy/h then the background noiseproducesfor100 nGy/h only 0.1 CPM. That means in 10 minutes ONEcounts in100minute TEN counts adding to the CPM0 (noise of sensor).So youneeda LONG time to measure for low radiation values onthisdevice.Attention: AM241 (smoke detectors) only emit ALPHArays,they getstuck in the plastic of the phones. H3 (tritium -watchesetc) arebeta emitters with 45 keV. They also get stuckquickly,mainlyalready in the watches. K40 (KCL for example contains16Bq/g) arebeta emitters with small amount of gamma (duetopositroncollisions)- you need also a long integration timetomeasure them.Same for TH rods (2% Thorium) mainly alpha rays,thenbeta and somegamma. Very small diameter ! You need a large areatodetect them(best GM with mica windows). The CMOS sensor ofthecamera only has2mmx2mm. Good objects are TH lenses (up to30%TH232), pitchblend(gamma of decay products) and CS137 forcheckingfood which mightbe contaminated (if larger 1 uSv/h).Don'texperiment withradiation sources !!! Features: * saving rawcountervalues in 3different noise levels * saving temperature data*saving location(optional) * saving settings data * export byemail(CSV) or file,CSV / HTML * export of mean values in Counts+standarddeviation *unit converter (Sievert, Gray, Rem...) Wejustreleased acomprehensive help on our homepage -- Important youNOISEvalueshould be similar as in our tables, if it is too highcheckthetape to cover the lense - use multiple tapes if necessaryandstartcalibration again !!!
