11.1 Technical Data
STS Safe-MiniSource (variable)
The STS Safe-MiniSource (variable) is a simulated radiation source for use with the Survey-Safe,
Safe-EPD & Dosi-Safe range of instruments.
The Safe-MiniSource (variable) is a variable activity source with a near isotropic field pattern, its
small size makes it easily hidden for carrying out training such as lost source recovery.

Additional Information
The STS Safe-MiniSource is not designed to be intrinsically safe and therefore should not be used in
hazardous environments. The units are not waterproof and contain delicate and sensitive electronics
which may be caused to fail if exposed to moisture. Units should be stored in a clean and dry
environment, batteries should be removed if storing for more than 4 weeks.
Instrument response will be affected by environmental conditions such as the presence of large
reflective surfaces, substantial metal structures and variable wall thicknesses.
