<p>PROBLEM TO BE SOLVED: To provide a device equipped with a radon gas generation source capable of generating radon gas efficiently.SOLUTION: A radon gas generator includes: a housing 10 provided with a suction port 11 and an exhaust port 12; a radon gas generation source 20 installed inside the housing 10; and a suction blower 30 installed inside the housing 10 for sucking ambient air from the suction port 11 and sending it to the radon gas generation source 20, and for discharging the radon gas generated at the radon gas generation source 20 from the exhaust port 12. Here, the radon gas generation source 20 is acquired by biscuit-firing a molded body formed by kneading powdery or granular radium ore with excipients and solidifying it at a maximum burning temperature of 500°C or higher and lower than 700°C.</p> |
