About

RADOM

Read full description

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.

How much radiation did your last flight expose you to? Find out... FlightDose is a scientific aviation tool for estimating exposure to cosmic radiation during flight, based on established aerospace radiation modeling principles. At its core, FlightDose leverages methodologies derived from CARI-7, a widely recognized aviation radiation dose model developed for analyzing radiation exposure at altitude. By combining route geometry with altitude, latitude, geomagnetic shielding, and solar conditions, FlightDose provides informed estimates of in-flight radiation dose in a clear, modern interface. Cosmic radiation increases rapidly at cruising altitudes and varies significantly by latitude and flight path. FlightDose makes this invisible environmental factor understandable using real aviation physics and data-driven calculations. What FlightDose does • Estimates in-flight radiation dose using CARI-7–based modeling concepts • Accounts for altitude, geographic position, and Earth’s magnetic field • Supports route-based and flight-based dose estimation • Presents results clearly without unnecessary complexity Who it’s for • Pilots and aircrew • Frequent flyers • Aviation professionals and students • Engineers, researchers, and science-focused travelers • Anyone curious about estimating radiation dose during flights Important information FlightDose is provided for informational and educational purposes only. It is not endorsed by the FAA and does not provide medical advice, diagnosis, or risk assessment. All dose values are estimates and should not be used for clinical, regulatory, or occupational decision-making. FlightDose Premium is available as an auto-renewing subscription: • Monthly: $4.99/month • Annual: $49.99/year Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.

Verdict

The call

The clearest difference is in-app purchases: RADOM at none against FlightDose's 1. RADOM also leads on ads (none vs shown) and iOS requirement (15.5 vs 17.0). FlightDose's advantage is update cadence (every 4 days vs every 8 months). On price and device support there is nothing between them.
