8.1 Technical Data
STS Safe-Series Field Survey Instruments
The STS Safe-EPD simulator is a simulated generic Electronic Personal Dosimeter designed to aid the tuition
of workers in the nuclear industry in safe practices and in understanding the accumulation of dose over time
but without exposure to radiation. The instrument operates using an STS radio frequency detection head
which detects the presence of a simulated radiation field with the resultant reading displayed on the LCD
Display. The instrument will work simultaneously with the Survey-Safe to provide a complete training
experience. Set-able alarm levels, background and chirp rates allow the user to create their own specific
training environment.

Operating & Storage
Temperature
The STS Safe-EPD 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.
