The instrument operates using an STS radio frequency emitter to generate a field which can be detected by the Survey-Safe or Dosi-Safe with the resultant reading  displayed on the LCD Display of the instrument. The Safe-MiniSource is designed to be easily hidden and features a single button to turn the source on/off and a led to indicate battery low. The Safe-MiniSource is a simulated radiation field generator which will generate a near isotropic field pattern providing a field of approx 15M in all directions.

​

The source features a single "isotope" which recreates the characteristics of the isotope in terms of its beta/gamma generation at a set activity level. The Safe-MiniSource runs off 2 standard AAA cells giving an operation time of over 10hrs. The Safe-Series of instruments offer the perfect solution for CBRN Training, Hazmat Training and Homeland Security Training with simple intuitive controls, competitive pricing and low ongoing cost of ownership.
