the radiation exposures as low as possible, but for planning purposes, if unanticipated yet cridible circumstances could result in
estimated doses in excess of 3.9 roentgens per year, then the detonations should be postponed until more favorable conditions
prevail.
Any past radiation exposures, from either nuclear weap-
ons tests or other activities at the Nevada Test Site, would be
included in estimating the total potential exposure fram any given
detonation.”
3.. The highest gross beta activity in the air was measured
at Alamo, Nevada, on July 14, 1962, amounting to 140,000 micromicrocuries per cubic meter.
Such activity in the air has no di-
rect interpretation in terms of radiation doses to persons but
serves to act as an alert for additional monitoring.
4.
Drinking water supplies showed no signficant increases
above those generally throughout the country.
5.
Detailed information on milk monitoring is contained in a
separate section.
