Dental Radiography: Radiation Protection

This set of flashcards covers essential terms and definitions related to radiation protection in dental radiography.

Radiation Protection

Measures taken to protect patients and operators from excess radiation exposure during dental imaging.

Collimator

A device that restricts the size and shape of the x-ray beam to reduce patient exposure.

Filtration

The process of removing low-energy x-rays from the beam, which helps decrease radiation dose to the patient.

Total Filtration

The sum of inherent and added filtration in an x-ray machine; regulated to ensure safety at specified kilovolt peaks.

Kilovoltage Peak (kVp)

The maximum voltage applied to the x-ray tube, influencing the energy and penetrating power of the x-ray beam.

Exposure Factor Selection

Adjustments of kVp, milliamperage, and time settings to minimize radiation received by the patient.

Thyroid Collar

A flexible lead shield that protects the thyroid gland from scatter radiation during x-ray exposure.

Lead Apron

A protective garment that covers the patient's chest and lap to protect reproductive organs from scatter radiation.

Maximum Permissible Dose (MPD)

The maximum amount of radiation a person may be exposed to during a specific period, ensuring safety.

ALARA Concept

Stands for 'As Low As Reasonably Achievable', emphasizing the importance of minimizing radiation exposure.
