What are the instruments used to detect radioactive materials?
RADIAC stands for Radiation Detection, Indication And
Computation.
A description is given of the main types of radiation monitoring
instruments, usually called "radiac" instruments, which would be
required by the civil defence authorities in the event of atomic
warfare. The instruments discussed include the flash dosemeter,
individual dosemeter, dose-rate meter and contamination meter. In
each case, an account is given of the purpose of the instrument and
the performance characteristics required, and some typical designs
are mentioned. The paper concludes with an appendix giving the
approved specifications for each instrument discussed.
