SUMMARY Thyroid dose (rads) to Rongelap girsls ages 3 to 4. Inhalation Oral Ingestion Most Min Max probable Whole-body 150 200 Radioiodine 200 Total 350 Most Min Max probable 175 150 200 175 1350 510 520 3300 1270 1550 685 670 3500 1445 4 The actual intake was undoubtedly a combination of the two modes of intake. The most probable dose is, therefore, in the range 700 to 1400 rad.
