In reviewing the data it shoulc be notec that where averase values are given, these are arithmetic means anc conservative values. The true mean is less than the arithmetic mean, since the distribution of radiological values ig either Poigeon or logarithmetic. Also it should be notec that some values are in terms of wet weights and others, dry weights. (For some Sam.les wet weights are difficult to determine re:iably), Wet to Gry ratios for various types of samples are of the order of 4to1lc. Also, the average value such as given in (4) and the inherent errors associated with lumping things together without consideration for the errors within or between species and within or between areas. The table of survey meter readings (1) lists maximum and average values at grounc¢ levels and at three feet above the ground, anc for gamma anc beta-gamma combined. The maximum value was 21 mr/hr for beta-gamma at ground level for an area about ten feet in ciameter (not a crater) on Rumurikku Island. In my conversation with Dr. Dunnam I commentec that perhars levels of raciation in a few smail areas might require the establisn- Ment of e:.ciusion areas, but upon looking at the other informa- tion fron thie area, thie conciusion may not have been justitiec.
