Removal of radioactive radon daughters from air |
| abstract |
An improved process for controlling radioactive radon daughters in the air in a working environment in a mine or during ore processing is described. The described process involving a filter for water contaminated with radon daughters is used in conjunction with air cleaning systems which employ water as a trap for radon daughters. The filter medium involves use of granular substrate which has been dried and oil-wetted with a normally-liquid hydrocarbon material. |
