Farmers cultivate plants in the winter using water curtain cultivation (WCC) facilities by spraying groundwater to keep them warm. In this study, WCC exhibited high radon concentrations during winter. The risk varied significantly depending on facility operation, peaking early morning and then decreasing upon ventilation. At all measurement sites, were low when was not used. Even period of use, if vapor condensation does occur, there is no significant difference from soil-only emissions....
Water-curtain cultivation (WCC) facility uses spraying groundwater to keep it warm. Direct of into the air makes radon gas in water diffuse air. To evaluate exposure on workers WCC facility, we continuously measured concentration, temperature, humidity, and pressure simultaneously during one whole period from Dec April 15 different facilities located southern area South Korea. We found accumulated when curtain operated at night. Radon concentration peaked just before facility's opening then...
