13.0 Portal Detector
13.1 Technical Data
The STS Portal simulator is a simulated radiation survey meter designed to aid the tuition
of workers in the nuclear industry in safe practices and in understanding the nature and
mechanics of ionising radiation.
The instrument operates using an STS radio frequency detection head which detects the
presence of a simulated radiation field, generated by the Safe-PocketSource, with the
resultant reading activating a LED beacon and sounder.

Operating & Storage Temperature
10 seconds from switch on to ready.
(variable activity level)
The STS Portal Detector 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.
