• Para.1.
• Para.2.

• Para.5.
• Para.6.
• Para.7
• Para.8

Most of the problems of an atomic car can be
summed up in one word radiation.
The prevention of radiation lies in the
invention of a metal strong enough to hold in
the rays and light enough to for a vehicle to
carry.
An economic engine should be made.
A road accident involving the atomic cars could
be just as dangerous as the explosion of a small
atomic bomb.
