抄録

An attempt was made to develop a new method to measure the bactericidal irradiance (253. 7 nm) accurately based on the silicon photodiode self-calibration technique. The absolute responsivity of a silicon photodiode was determined at 632.8 nm with self-calibration technique. The absolute responsivity at 253. 7 nm of the photodiode was determined by the relative spectral responsivity measurement using a spectral responsivity standard which is a thermal detector. Pure bactericidal radiation was generated from the combination of a bactericidal lamp (GL-15) and an interference filter which has a pass-band of only around 253. 7 nm, and its irradiance was calibrated using the silicon photodiode with an aperture of known opening area. Using the calibrated radiation, any bactericidal irradiance detector can be calibrated accurately.
