Radiation varies
with location,
weathering causes
changes in concentration
*§ nautical miles from ground zero.
e
tAssuming that radiation decay follows aT~'-* law, extrapolation indicates
that rardiation readings of greater than 2300 r/hr would have existed at H + i br.
Limited recovery (10 min) could commenceat H + $6 hr.
