The set FH 40
D is designed for use by customs inspectors, police, and other security and
anti-terrorists task forces.
It is a powerful tool for:
- detection of contraband hidden in cavities
- detection of illicit transports of nuclear material
- measurement of local gamma dose rate and dose
Cavities filled with cigarettes, drugs, explosives and other organic compounds
containing a high amount of light elements like hydrogen, carbon and other elements with
low atomic mass can be positively detected. Penetrating gamma radiation is used to look
through covers of steel, aluminium, ... Specially light elements will backscatter a
considerable amount of radiation to the detector -- this is used as indicator.
FH 40 D can't tell you what it is, but it will indicate that there is something which
shouldn't be there.
Likewise nuclear material can be detected in places where no radiation is expected to
be, by searching with the gamma detector alone - a highly sensitive NaI-scintillation
detector. This detector is 150 times more sensitive than a good 'standard' gamma survey
meter!
