The objectives of Project 2.66 were to determine:
1.
The variations in chemical and radiochemical composition of
2.
The chemical and radiochemical nature of liquid fallout and
solid fallout with particle size, zero-point environment, and time
and distence of collection.
base surge, if formed.
3. The manner in which gross decay rates are affected by
variations in radiochemical composition.
1.1.1
Purpose
The purpose of obtaining these data was for use in studying
basic problems of fallout phenomensloyy. The ultimate objective of
this and +imilar work is to ebtain data which may be used to develop a
theory for the prediction of the military effects of operaticnal
nuclear weapons under specific conditions. Data obtained to meet the
first objective may be used to aid_in the development of a model of
fireball dynamics in relation to particle formation, Liquid fallout
was also studied to gain further insight into the history of the fallcut materiel after its formation, and for documentation of internal
radiation hazards.
An investigation was carried out on the relation
between decay rate and radiochemical composition because it appeared
that 1t might be applicable to the problem of predicting the decay
characteristics of fallout material from any operational detonation.
