## What is RADOM?

Radiation Dosimeter Monitor (hereinafter referred to as RADOM) App is an application that monitors radiation measurement values in real time by connecting to radiation detection devices developed by JS TECHWIN Co., Ltd. via Bluetooth.

1. In order for the RADOM App to work, it is necessary to connect to the radiation detection device of JS TECHWIN Co., Ltd. via Bluetooth.

2. The real-time measured radiation dose is displayed on the screen of the smartphone so that the user can check the value, and a warning notification sounds for the radiation dose whose converted value exceeds the annual radiation exposure allowance.

3. The measured radiation dose is stored in the internal memory of the smartphone where the App is installed along with the user's location information, and the measured radiation dose can be viewed by running it again at any time.

4. The stored radiation dose can be checked by year, month, day, and hour.

5. Radiation exposure for the last year can be checked separately, so it is possible to check whether an individual has exceeded the annual radiation exposure limit.
