Exam 19: Radiation Benefits and Risks of Medical Imaging

Which of the following cancers are associated with high levels of ionizing radiation exposure?

The Image gently campaign promotes education of parents and health professionals to reduce unnecessary radiation exposure in children.

The latent period for adverse health effects from exposure to high doses of ionizing radiation may range from several years to decades.

About half of the annual per capita radiation exposure in the United States is from natural background sources such as from the air, ground, water, food, or building materials.

Exposure to medical sources of ionizing radiation has increased by more than seven times in the last few decades.

The controversial and most conservative assumption for health effects of ionizing radiation at exposures of less than 10 mSv is called:

The "Stark Law" and requirements of the Patient Protection and Affordable Care Act make it easier for healthcare providers and hospitals to have financial ownership in medical imaging facilities.

Adverse health effects from exposure to high doses of ionizing radiation may include both acute and chronic health risks, as evidenced from the Chernobyl nuclear power plant accident.

Data from the Dartmouth Atlas show higher radiation exposure for children were documented in which of the following areas?

The absorbed dose, measured in grays is multiplied by a weighting factor to calculate a dose equivalent, measured in Sieverts.

Many medical and experts express concerns about CT scans because of trends of increasing use and resulting increases in population ionizing radiation exposure.

Of the per capita exposure to the U.S. population from man-made sources, nearly all comes from:

The National Institutes of Health Clinical Center requires that radiation doses from medical imaging be recorded in patients' medical records.

Which of the following are examples of ionizing radiation?

Which of the following organizations are involved in oversight or education about ionizing radiation?

Of the different types of medical imaging studies, which of the following results in the exposure equivalent to the highest number of chest X-rays?

An initiative of the American Board of Internal Medicine Foundation to enhance conversations between physicians and patients, and reduce unnecessary testing is called:

Concerns from medical and public health experts about risks from increasing radiation exposure from medical imaging focus on:

Estimated annual U.S. population exposure to radiation is now about:

Variation in use of medical imaging has been documented in different healthcare settings, in different geographic locations, and even with use of the same medical test.
