The Nuclear Radiation Detector app is a specialized tool designed to work in conjunction with a Geiger counter, a device used for detecting ionizing radiation. This app, however, does not detect EMF (Electromotive force) or electromagnetic force.

To utilize this application, you need a DIY or pre-existing Geiger counter that supports Arduino connectivity. The app then serves as the interface for your Geiger counter, displaying crucial data such as readings of radiation levels.

One of the key features of the Nuclear Radiation Detector app is its ability to visually represent CPM (counts per minute) and uSv/h (microsieverts per hour) readings. Additionally, it offers a mapping feature using Google Maps, allowing users to chart radiation levels across different areas.
