STUDY ON ENTRANCE SKIN DOSE AT PANORAMIC RADIOGRAPHY IN INCHEON, KOREA

Abstract

Recently, the use of panoramic radiography has shown a constant increase, and significant research is underway. However,radiation exposure attracts less attention in dental radiography than in other types of radiography. We used an OSLD formeasurement of the entrance skin dose in eyeballs and the thyroid region, both of which are not covered by examinationsbut are included in radiographical regions and are sensitive to radiation, as well as orally in Incheon and reported the results. The entrance skin dose was 0.0282 mSv on average for the oral region, and 0.0259 mSv on average for the eyeball, and0.0261mSv on average, for thyroid gland. While there is no proper shielding method for the eyeball, a thyroid protector isnot used by most hospitals and most hospitals are equipped with an apron and a thyroid protector separately; thus, it isnecessary to use an integration of an apron and a thyroid protector and medical device manufacturers need to develop a methodfor controlling the length of the slit in the slit-type area of radiation occurrence in order to reduce unnecessary exposure.
