| Abstract | ||
| Aims: To encountered in using thermopile device (thermocouple) as densitometer for measuring opticaldensity for X–radiation film which is used in dental medicine. Materials and methods: Americium–241(Am–241) 59.5keV was used to expose a number of dental X–ray films for different times toend with a variety of optical densities on them. Results: A comparison of the optical density readingsbetween the densitometer and thermopile was made. Conclusions: The thermopile was capable tomeasure the optical density of any transparent polymer material while the densitometer can measurethe optical density of the X–ray film only. | ||
