Description

This is a real working radioactivity counter.The LITE version show only COUNTS and dont need calibration. TheApp is using the camera sensor to detect radiation. We testedseveral mobile phones at the Helmholtz research facility using aprofessional raditation device in the range of 2 µG/h till 1-10µG/h. For the LITE version you can use our tables for a roughtranslation of counts/h to MikroSievert/h or MikroGray/h.

You can use the email button in the help menu to provide us withfeedback and please use it.
The app can log counter values and the resulting statistic can besent by email (Csv) or saved as csv or html file.

On our homepage you find a complete manual (for the FULLversion) and more Infos.

Disclaimer: The type of radiation picked up by the camera can bedangerous/detrimental to the user's health as well as cause damageto the device.

Radioactivity Counter 2.1 APK
Rolf-Dieter Klein
Radioactivity Counter This is a real working radioactivitycounter.You only need a BLACK TAPE to cover the lenses !!Disclaimer: Thetype of radiation picked up by the camera canbedangerous/detrimental to the user's health as well as causedamageto the device. Its NOT a JOKE! The App is using the camerasensorto detect radiation, like a geiger mueller counter, of coursewitha smaller area. We tested several mobile phones at theHelmholtzresearch facility in Munich, using a professionalradiation devicein the range of 2-10 µGy/h till 1-10 Gy/h (CS137and CO60). TheCMOS sensors can detect primary gamma radiation andsome higherbeta radiation (depends on the shieldings in the mobilephone).Typically not going into saturation as most GM tubes. SeeFAQ onour homepage for what you can measure and how. PLEASE SENDUSFEEDBACK via EMAIL !! We add new devices in shortintervals.Attention: the tape must shield the light completely.Please checkwith a light source ! On our homepage you find severalmeasurementresult for different devices we tested so far. Some areexcellent,some not that sensitive. Feel free to use our table toassignradiation values to our counter measurements when you havethe samedevice. The real values might differ as sensors can change.Therewe need your help and the help of the manufactures for afuturecalibration service. You can use the contact button in thehelpmenu to provide us with feedback and please use it. If you needanyhelp, PLEASE send us an email. We have cannot answer thecommentsection below, so please ask us first on measurmentproblems. Wehelp as fast as possible. Please contact us on anyproblems youhave with this application! Look at our videos, moreare commingsoon. Attention: The counts per minute (CPM) for thebackgroundnoise should be low (increase the noise setting if not).This iscamera noise not radiation noise basically. If theradiationincreases then also counts from the radiation adds to theCPMvalues (see our tables for the sensitivity). If you have aphonewith 200 CPM for 100 uGy/h then the background noise producesfor100 nGy/h only 0.1 CPM. That means in 10 minutes ONE counts in100minute TEN counts adding to the CPM0 (noise of sensor). So youneeda LONG time to measure for low radiation values on thisdevice.Attention: AM241 (smoke detectors) only emit ALPHA rays,they getstuck in the plastic of the phones. H3 (tritium - watchesetc) arebeta emitters with 45 keV. They also get stuck quickly,mainlyalready in the watches. K40 (KCL for example contains 16Bq/g) arebeta emitters with small amount of gamma (due topositroncollisions)- you need also a long integration time tomeasure them.Same for TH rods (2% Thorium) mainly alpha rays, thenbeta and somegamma. Very small diameter ! You need a large area todetect them(best GM with mica windows). The CMOS sensor of thecamera only has2mmx2mm. Good objects are TH lenses (up to 30%TH232), pitchblend(gamma of decay products) and CS137 for checkingfood which mightbe contaminated (if larger 1 uSv/h). Don'texperiment withradiation sources !!! Features: * saving raw countervalues in 3different 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 justreleased acomprehensive help on our homepage -- Important you NOISEvalueshould be similar as in our tables, if it is too high checkthetape to cover the lense - use multiple tapes if necessary andstartcalibration again !!! Please before writting a bad one starcommentwrite us we will help you very quickly PLEASE !!! morevideos onour homepage - instruction andhelp:http://www.youtube.com/watch?v=qJcOq5sLxPo somemore:http://www.youtube.com/watch?v=MsG6JsMAJ_Q

Ports Of Call Classic 2.2 APK
Rolf-Dieter Klein
Finally Ports Of Call the classic trade simulation game fromtheAmiga time made it onto Android devices. We tried to be as closeaspossible to the orginal (its really the SAME kernel code), intermsof original grafic and behavior. We added some helpfulfeatures, asthe new joystick control for navigating in theshipsimulator andfor the radar collision system. We also added somekeyboard supportwhen a keyboard is not available. Save, Load, Helpand New isavailable using the Android MENU item. We tested the gameondifferent devices, also very small ones. The buttons aresometimessmall, but you will get used to them, but therefore wewere able touse our original grafics with the typical AMIGA look.We providedan intro and tutorial video. The App supports 10differentlanguages which can be selected when starting the game(English,French, Netherland, Norwegian, Italien, Spanish, Finish,Swedish,Daenish, Portugais and German). Any suggestions are welcomepleasewrite us. Some hints on comments and the EXIT function oftheprogram. Please use the HOME button to exit the application.Wedidnt provide an extra EXIT button to terminate the program, astheAndroid System recommends not to terminate the programourselfinstead let do the Android System the termination ifnecessary.This is to have a full compatible system and keep the OSin astable condition. We prefere a stable system left to theuserinstead of doing some hacks on this -- if you really need tokillthe App, use the END program function of the AndroidApplicationmanager, so you dont need to reboot the Phone. Also usedin navalschools for education. features in the last rev 1.4: 1.Backspacealso can be used as the OK button, to LOAD the ship in thecaptainswall and to START or STOP the simulation in the mainscreen. 2.Buttons - User Interaction. New algorithm for handlingall buttons.Now a radius region is searched, which gives a muchbetterresponse. Better behavior at the border. 3. bug fix for soundnotterminating when the program is exit (e.g. paused). 4.Fixedproblem with the timeout message and text. Please also writeanemail if you have error messages or problems. We want tohelpquickly, but you need to write an email to us with details.Thecomment section is a bad place as we cannot reply or askquestionson the problem. We really want to help.
