Abstract:

The objectives of research now in progress are 1 to estimate the extent to which vegetation has been destroyed or damaged by cratering, blast, andor throw-out, 2 to study the re-establishment of vegetation in areas where the original vegetation was completely destroyed and the surface covered by a foot or more of radioactive throw-out, 3 to study the recovery of vegetation which was damaged but not destroyed by blast andor throw-out, and 4 to study the effects, if any are detectable, of the exposure of plants to gamma radiation and to heavy deposits of radioactive dust derived from the base surge cloud.
