Verification of the applicability of the RAD7 radon monitor to the solid radon source exhalation reference model

Nuclear Engineering and Technology
The RAD7 radon monitor, based on the electrostatic collection method, is sensitive to humidity during measurements, necessitating the use of a desiccant to maintain the relative humidity in its built-in chamber less than 10 %.

Radon exhalation rates corrected for leakage and back diffusion – Evaluation of radon chambers and radon sources with application to ceramic tile

Journal of Radiation Research and Applied Sciences, 2014
The natural radon decay, leakage and back diffusion are the main removal processes of radon from its container. Ignoring these processes leads to underestimate the measured value of radon related parameters like exhalation rate and radium content.

International standardisation work on the measurement of radon in air and water [PDF]

, 2017
Radon is considered to be the main source of human exposure to natural radiation. As stated by the World Health Organization, the exposure due to the inhalation of indoor radon is much greater than the one via the ingestion of water as radon degasses ...

Traceable measurements of the activity concentration in air [PDF]

, 2001
The nuclear reactions induced by high energetic protons in heavy targets such as UC/sub 2/ and ThC cause a particular, complex radiation protection task at facilities like ISOLDE: the measurement of a mixture of different isotopes of the radioactive ...
