"Fungi" - A Radon Measuring Instrument with Fast Response

The FUNGI uses an electrostatic field to collect the daughter products of radon decay, and a solid state detector to resolve the energies of radium A (218po) and radium C' (214po) alpha particles. This permits a great degree of flexibility in the measurement of radon and radon daughters. In addition, by limiting the instrument response to the radium A channel only, the response to changes in radon concentration of this instrument is ten times faster than other instruments, making it suitable for radon survey applications.
