PROBLEM TO BE SOLVED: To provide a dust radiation monitor which measures the intensity of the radiation included in the dust in the atmosphere, can be operated with no periodic maintenance and without using consumables, does not require an apparatus and a component such as a suction pump and a pipe, is small-sized and lightweight and usable as a portable type, generates no noise, and gives a low burden to the environment and people. SOLUTION: This dust radiation monitor introduces the atmosphere under test including dust and ionizes the introduced atmosphere under test. An electric field is applied to the atmosphere under test including dust electrified by the ionized atmosphere under test, the electrified dust moved by the electric field is stuck, and the radiation discharged by the stuck electrified dust is detected.
