The plant for obtaining an aqueous radon solution.

Developing indicator methods to determine the main characteristics of cores extracted from oil-bearing strata presupposes simple, radiation-safe installations of an aqueous radon solution. This study describes such an installation, comprising crushed uranium ores weighing ~45 kg. Herein, we investigated the radon concentration (RC) of water as a function of pumping rate and duration to determine the optimal pumping conditions necessary for achieving a maximum RC in water of ~3 kBq/L.
