Solutions to Common Questions

Not with RAD7. The RAD7 uses electrostratic precipitation with a sophisticated silicon detector and high-resolution alpha spectroscopy to clearly differentiate between signal and noise. Therefore, unlike radon monitors that use pulse ionization chambers, the RAD7 easily differentiates between radon and thoron, and its low background remains low for the life of the instrument. View how the technology works. Note: this paper was introduced at the NORM IX symposium and will be included in the proceedings.
