  • What's Included
  • Determine the amount of radioactive particles around you with the Lapka Radiation Sensor and an iOS smart device (iPhone 4 and higher, iPad, iPod Touch 3rd generation and higher) running the Lapka app. This tiny, handheld Geiger Muller counter connects to your iPhone, iPad or iPod touch with an included cable to quickly begin displaying for you the amount of hard beta and gamma particles you are being exposed to. Begin running the two minute air quality test on the app to initiate sampling and to yield more precise, accurate results allow it to continue to run; the longer it runs, the larger the sample size and the more accurate your reading will be. As you begin to move around you can see the various particles appear on the screen of your iOS device and now determine which areas have the greatest amounts of radiation and the lowest amounts. The Radiation Sensor comes with a list of preset scenarios, places and situations that it recommends you to measure the radiation levels of such as your home or office. Upon running the test you can save the generated data so that it can be shared, viewed later to determine if levels are getting better or worse, or to help yourself remember which locations to avoid due to larger radiation particle exposure.

    Lapka App
    • Ambient Mode - At the bottom of your screen you'll notice animated particles moving around that match the symbol of the sensor you're using. These are representations of every particle counted in your environment allowing you to visualize your environment in real time.

    • Diary - Saves your results. They'll be stored in your Lapka diary as little blocks, which you can access when a device is not plugged in. Give your iPhone a shake and the blocks will shift from device used to preset used to the type of result. You can review each moment you captured in an individual day or explore by month.

    • Share - There are various options for sharing your measurements. Email an office measurement to your employer who's thinking of getting some humidifiers for the workplace. Text a radiation result to a family member, letting them know you're safe and sound. Tweet about how fresh and delicious your apple is. Or simply choose to copy the result and paste it anywhere you feel like. When you share, a link is provided that brings you to a beautiful, animated visualization of the moment you captured. If your result is saved to your diary, you can always share it later.
