Survey of Radon Concentrations in the University of Granada in Southern Spain Calvente, Irene Núñez Torres, María Isabel Chahboun Karimi, Rachid Villalba Moreno, Juan Radon health effects Indoor radon levels Radon exposure Ventilation The objective of this pilot study was to gather and analyze data on radon concentrations in workplaces in three buildings of Granada University (Southern Spain) constructed in different centuries. All measurements were made at basement or ground floor level under normal use conditions except for one space (mineral store), in which measurements were compared between the door closed and open. Measurements were conducted during different time periods between October 2013 and March 2019 with a Radon-Scout PLUS portable Radonmonitor. The duration of continuous recordings at different sites ranged between 42 and 1104 h. Mean accumulated radon concentrations ranged between 12 and 95 Bq/m3 , below the maximal level of 300 Bq/m3 set by the World Health Organization (WHO). Relatively high values were recorded in the oldest building (15th century), which was also poorly ventilated. Ventilation appeared to be an important factor in reducing radon levels, especially in areas less exposed to radon, such as Southern Spain. 2021-05-24T11:14:18Z 2021-05-24T11:14:18Z 2021 info:eu-repo/semantics/article Calvente, I.; Núñez, M.I.; Chahboun Karimi, R.; Villalba-Moreno, J.
