 note = {P(論文), The measurement of natural radon is important in geochemical and environmental studies. A method for simple measurement of radon, especially suitable for field observation, was investigated. Cellulose nitrate film (Kodak, LR. 115,Type II) was used for detector. This film is insensitive to β, γ and light radiations and to α activity plated-out on its surface. A cylinder with heater was used for film exposure fixture. The film at the completion of exposure was etched in 10%-NaOH (60℃, 150 min.), washed, dried and counted with a 40X optical microscope. At test in Okayama University of Science atmospheres, radon concentration of 6.2-64.5 (tracks/cm^2・day) was observed by this device.},
