Abstract

We examined the transmittance of FIR on 35mmφ plastic petri dish for tissue culture
The transmittance was 18% at 8.87μm, 10% at 11.5, 12.2 and 15.5μm.
From these results, it was found that although the transmittance was low, FIR could transmit the plastic petri dish, and it was suggested thet FIR exactly affected the functions of tooth germs.
