  • Non-pressurized ion chamber
  • Double mylar for better beta response
  • Measures body dose or skin dose

The ion chamber IC3 is a vented portable ion chamber that changes the measurement range automatically depending on the dose rate, no manual setting is needed. Measures dose or dose rate for gamma, x-ray and beta radiation. The model has double mylar windows, which improves the measurement properties for beta and low-energy gamma. Perfectly suited for radiation protection applications where surface dose or pulsed radiation fields are the focus. IC3 can handle pulses down to 50 ns, making it the unit for flash X-ray measurements in NDT (non-destructive testing).
