The effective dose (EfD) limiting system is
a method used by the Nuclear Regulatory Commission to determine whether users of radioactive substances are in compliance with the provisions of their license.
a method used by the Federal Drug Administration to conduct an ongoing product radiation control program.
the current method for controlling the risk of biologic damage to radiation workers and the general public from radiation exposure.
responsible for the development of the radiation hormesis theory.
The ALARA concept adopts an extremely conservative model concerning the relationship between
health care education and radiation research.
ionizing and nonionizing radiation.
ionizing radiation and potential risk.
radiation dose and health care spending.
If a certain dose of radiation produces a skin burn, a higher dose of radiation will cause the skin burn to be more severe; however, a dose below the threshold level for skin burn will
demonstrate this effect to a much greater degree.
demonstrate this effect to moderate degree.
demonstrate this effect to a lesser degree.
not demonstrate the effect.

5 mSv.
15 mSv.
50 mSv.

Whenever the letter “M” appears under the current monitoring period or in the cumulative columns of a personnel monitoring report, it signifies that a (an)
mistake has been made in recording the equivalent dose.
equivalent dose higher than the minimum measurable radiation quantity was recorded during that time.
equivalent dose below the minimum measurable radiation quantity was recorded during that time.
maximal equivalent dose has been exceeded during that time.
Three different filters are incorporated into the detector packet of the optically stimulated luminescence (OSL) dosimeter. These filters are respectively made of 1. aluminum. 2. copper. 3. molybdenum. 4. rhenium tungsten. 5. tin.

The front of the white paper packet of the optically stimulated luminescence (OSL) dosimeter
may be color coded to facilitate correct usage and placement of the dosimeter on the body of occupationally exposed personnel.
must not have any type of printing on it.
must be radiopaque.
must never be exposed to ionizing radiation.
The personnel direct ion storage dosimeter provides an instant read-out of dose information when connected to a computer via a connector such as a (an)
universal serial bus (USB).
charge-coupled device.
electrometer.
ionization chamber.
Which component(s) of the Geiger-Muller survey meter alerts the operator to the presence of ionizing radiation?
The shield covering the probe’s sensitivity chamber
An audio amplifier and speaker
The metal that encloses the counter’s gas-filled tube
The meter scale
Which of the following are disadvantages of the TLD ring dosimeter?
Thermoluminescence readings will be lost if not carefully recorded.
The readout process destroys information stored in the TLD ring dosimeter, thus preventing the "read" from serving as a permanent legal record of exposure.
Calibrated dosimeters must be prepared before-hand and read with each group of TLDs as they are processed.
All of the options.
