CLINICAL MEDICINE

Detailed explanation-1: -The harmful biological effects of ionizing radiation on the human body are well known. It is therefore necessary to strive to reduce radiation exposure. Lead aprons with thyroid shields are the most fundamental radiation protective devices for interventional procedures, and are very effective.

Detailed explanation-2: -Shielding-Attenuation of radiation exposure by protective devices between the source of radiation and the exposed individual. It includes personnel shielding and patient shielding of organs not under investigation. Personnel shielding devices includes lead apron, lead goggles, gonad shields, thyroid masks and gloves.

Detailed explanation-3: -Thyroid collars should be used in all examinations where the thyroid may be exposed to the main beam or to a considerable amount of scatter radiation. Lead aprons must be provided for a person who is required to support a patient during the radiographic procedure (i.e., a comforter or carer).

Detailed explanation-4: -It is well known that the thyroid collar is an effective shielding device for the protection of the thyroid gland from exposures to intraoral radiographs.
