451B Ion Chamber Survey Meter with Beta Slide
The 451B ion chamber survey meter is a handheld battery operated unit designed for use in both rugged and normal environments. The 451B includes a sliding beta shield to serve as an equilibrium thickness for photon measurements and enables beta discrimination. The 451B auto-ranges and measures radiation rate and accumulated dose from various radiation sources (alpha, beta, x-ray, gamma). The ion chamber detector allows for a fast response time to radiation from leakage, scatter beams, and pinholes. Additionally, the low-noise chamber bias supply provides for fast background-settling time.
