Therefore, there ia a gap between 2 ev. and 3 MEV that is not being measured, There is avidence from the Greenhouse work to indicate that there is bielogical damage which is believed to be from the neutron in the range. ide have requested that copies of the Greenhouse report and the Shelter Test report bs sent to you, and they abould be there within the next few days. 4s you can see from this letter, things are beginning to shape up to a point whereby we should be able to give you the distance from the bamb, expected radiation doses, sta. within the next few weeks,
