IHS Test 2 - Radiation Principles and Hazards

Radiation exposure is measured in [blank_start]REM[blank_end] (use abbreviation).

Which of the following is NOT a source of non-ionizing radiation?

Which of the following is not an example of ionizing radiation?

Frequency and wavelength are [blank_start]inversely[blank_end] related. The shorter the wavelength, the higher the frequency.

Select the description as being for particulate ionizing radiation for a or b. [blank_start]a particles[blank_end] lose energy quickly [blank_start]b particles[blank_end] have a longer range than other particle types [blank_start]b particle[blank_end] examples include positron emission tomography scanning [blank_start]b particle[blank_end] examples include Strontium 90 used in radiation therapy for eye cancer [blank_start]a particle[blank_end] can be stopped by piece of tissue paper or dead skin [blank_start]b particle[blank_end] can be stopped by thin sheet of plastic, aluminum, or span of air [blank_start]a particle[blank_end] isn't very hazardous from external exposure

[blank_start]Electromagnetic ionizing radiation[blank_end]'s two primary types are y rays and x rays. It travels at the speed of light and behaves like a wave and a particle.

[blank_start]X rays[blank_end] are artificially produced [blank_start]Y rays[blank_end] are emitted from nucleus during radioactive decay

[blank_start]Gamma rays[blank_end] are given off in radioactive decay accompanying alpha and beta particles.

Which of the following isn't a medical use for gamma rays?

The inverse square law applies to:

The maximum yearly occupational exposure is no more than what number of REM/year?

Radiation exposure should be As low as reasonably achievable ([blank_start]ALARA[blank_end]).

What is the recommended distance away from a patient during an X-ray?

[blank_start]LASER[blank_end] stands for: light amplification by stimulated emission of radiation.

Name the three ways (alpha order) that Laser light is different from visible light: [blank_start]Coherent[blank_end] [blank_start]Collimated[blank_end] [blank_start]Monochromatic[blank_end]

[blank_start]Eye injuries[blank_end] are the greatest risk for OR personnel.

Match the eye shield color with the laser type: CO2 lasers : [blank_start]Clear[blank_end] ND:YAG lasers: [blank_start]Green[blank_end] KTP lasers: [blank_start]Orange-red[blank_end] Argon lasers: [blank_start]Orange[blank_end]

A pregnant anesthesia provider shouldn't be exposed to which radiation type? [blank_start]Magnetic resonance imaging[blank_end]

The most significant injury risk in the MRI suite is:
