. Integrating the dose rate over time produced a total effective dose to persons on the ground of about 0.6 mSv (wr and wT = 1.0)

As seen in Figure C.2, the external dose received by residents of Guam from the test was about 20% of the annual effective dose received from natural background radiation in the continental United States and about 50% of the annual effective dose received from current values of natural background in Guam. To gain an appreciation of the fallout received from other tests, we used data from the ground-based monitoring stations.
