A free program for Android, by Nitramite.

This is a free, easy-to-use, fast, and reliable application for measuring the amount of radiation that you are exposed to.

The app is based on the Geiger counter, which was developed by the U.S. National Institute of Standards and Technology (NIST) and the National Radio Quiet Zone (NRQZ). It is used for measuring the amount of radiation that you are exposed to.

This app can be used for detecting radiation from the environment, such as from the sun, the earth, or other sources. It can also be used for measuring the amount of radiation that you are exposed to while inside the body, such as while you are in the hospital, at the workplace, or while traveling.

It is designed for use with a personal dosimeter that has been calibrated with a standard, such as the Raden STBA-66.
