This fundamental equation, developed by Albert Einstein, describes the relationship between mass and energy
What is E=mc²?
100
This American inventor developed the fluoroscope in 1898, allowing real-time imaging of internal structures.
Who is Thomas Edison?
100
This term refers to the reddening of the skin due to high radiation exposure, an early sign of radiation damage.
What is erythema?
200
This organization, founded in 1920, is the world's largest membership association for medical imaging technologists and radiation therapists.
What is the American Society of Radiologic Technologists (ASRT)?
200
This principle ensures that radiation exposure is kept as low as reasonably achievable to protect patients and personnel.
What is ALARA?
200
This form of energy results from the movement of electrons through an electrical potential difference, as seen in an X-ray tube.
What is electrical energy?
200
This Boston dentist was one of the first to introduce radiation protection measures, including collimation and filtration
Who is William Rollins?
200
This condition, often linked to radiation exposure, results in the abnormal overproduction of immature white blood cells
What is leukemia?
300
This term refers to the total ionizing radiation energy absorbed per kilogram of matter and is measured in Grays (Gy).
What is absorbed dose?
•Gyt
•Absorbed dose is the radiation energy absorbed per unit mass and has units of J/kg or Gyt.
•RAD
•The units Gya and Gyt refer to radiation dose in air and tissue, respectively.
300
This measurement is weighted using tissue weighting factors (wT) to estimate the overall risk of harm to the body.
What is effective dose?
300
This type of radiation consists of high-energy, high-speed electrons or positrons emitted during radioactive decay
What is beta radiation?
300
This scientist introduced the Snook Transformer in 1907, providing a high-voltage power supply for X-ray production
Who is H.C. Snook?
300
This SI unit is used to measure occupational radiation exposure and effective dose, taking into account radiation type and tissue sensitivity
What is the Sievert (Sv)?
400
This agency sets certification and registration requirements for radiologic technologists and ensures they meet education, ethics, and examination standards.
What is the American Registry of Radiologic Technologists (ARRT)?
400
This type of radiation damage occurs at the cellular level and can lead to mutations, cancer, and other long-term health effects.
What is stochastic effect?
400
This SI unit measures the radiation energy absorbed per kilogram of tissue and is commonly used in medical dosimetry
What is the Gray (Gy)?
400
This vacuum tube, introduced in 1913, allowed for better control of X-ray intensity and energy, revolutionizing radiology.
What is the Coolidge Tube?
400
This period refers to the time between radiation exposure and the appearance of harmful biological effects
What is the latent period?
500
This unit, named after a French physicist, measures the rate of radioactive decay or activity of a substance.
What is the Becquerel (Bq)?
500
This organization is responsible for certifying and registering radiologic technologists by overseeing education, ethics, and examination requirements.
hat is the American Registry of Radiologic Technologists (ARRT)?
500
This type of radiation consists of electromagnetic waves with no mass or charge and is emitted from the nucleus of a radioisotope
What is gamma radiation?
500
This invention by Gustov Bucky in 1913 and later improved by Hollis Potter helped reduce scatter radiation in X-ray imaging.
What is the Bucky-Potter Grid?
500
Radiation-induced effects can be classified into these two categories: one affects the exposed individual, while the other affects future generations.
What are somatic and genetic effects?
