抄録

Recently the Japanese Industrial Standard on HEPA Filters for radioactive aerosols (JIS Z 4812) was revised, in which the standard particle size was changed to 0.15μm from 0.3μm. A new 0.15μm DOP aerosol generator was developed for in-place filter testing. The aerosol generator is of the vaporization-condensation type. The generated DOP aerosol were found to be quasi-monodispersive with a geometric standard deviation (σg) of less than 1.2 by laser aerosol spectrometer measurements. A typical size distribution of test aerosol was a count median diameter (CMD)=0.151μm and σg=1.15. The number concentration was 1.4×10⁴/cm³ at an air flow rate of 7, 800m³/h. The stability, portability and operability of the new generator were also evaluated.
