REMARKS:
The survey readings of the shot island, Janet, were obtained by the
Radiological Safety Organization at H+24 and H+72 hours and extrapolated
to H+l hour by the t-1** decay approximation.
Most readings were
obtained from a helicopter flying at an altitude of 10 to 20 feet and
the observations were considered representative of readings 3 feet
above ground.
Such resdings may be low by 20 to 50 percent.
