| Objective To investigate the radiation level around Jiangzha hot spring, and to analyze the sources of pollution. Methods The radon and its progeny concentration,γ dose rate in hot spring living district and surrounding area were measured with ATD monitors, radon and WL continuous measurement devices, γ dose rate meter. Results The radon concentration in water was 23-764 Bq/L. Radon concentration indoors, outdoor and in bathing place were 254-876 799, 688-709 and 3590-15299 Bq/m3, respectively.γ dose rate were 205-28718 nGy/h indoor, 4104-18254 n Gy/h outdoors. Conclusions Jiangzha hot spring is an area with rare high radon and high nature radiation. Its radiation level and health effects are worthy for further attention. |
