To explore effects in this area would required
explosions about as follows:
High yield at about 450,000 feet for effects in the D-region.
Righ yleld at about 1,500,000 feet for effects in the upper ionospheric region.

High yield at about 3,500,000 feet to understand effects associated
with magnetic containment and disturbances.

Anti-ICeM Effects
The kill mechanisms for anti-ICBM systems must be better defined.
These include X-rays, neutrons, and possibly thermal and blast effects.

under actual environmental conditions as well as to search for unexpected
phenomena, it seems impossible to avoid the necessity of high altitude
bursts.

At the present time no specific experiment has been designed.
Atomic DemoJition Munitions
- Of less over-all importance but of
considerable interest for atomic demolition purposes and PLOWSHARE
(excavation), cratering explosions would be required to measure the throwout and distribution of radioactivities from such underground detonations.
In this case experiments can be designed in such a way that the fallout
that does occur will be highly localized (for example, to the test site
in Nevada}.
As part of the PLOWSHARE program two cratering experiments
have been designed, one at 500 tons inhard rock at the Nevada Test Site
