How to calculate your external gamma dose

To begin, draw a rectangle on the map representative of the area visited. Click the map to place markers for the upper left corner and lower right corner of the rectangle. Next, click "Draw". A rectangle will appear on the map. Make sure the rectangle includes at least one data point, then click "Submit". Fill in the displayed table and click "Submit". Your radiation dosage will be calculated and displayed. For comparison, the natural background radiation dose in the Marshall Islands is 1.9 mSv (190 mrem) per year. You can calculate multiple doses per session and all calculated doses will display until you end your session. To end your session, click "End Session" at the top of the page.
