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.

Which of the following instruments is called a cutie pie?

Some of the advantages of the optically stimulated luminescence (OSL) dosimeter are 1) can be used for up to 1 year. 2) lightweight,durable,and easy to carry. 3) integrated,self-contained,preloaded packet.

Which of the following are advantages of the personnel digital ionization dosimeter? 1) Instant access to reports 2) No waiting time for mailing dosimeters 3) Lightweight and durable 4) Can be dropped or scratched with little chance of harm to the device

An ionization chamber connected to an electrometer is a device that can measure

The digital ionization dosimeter provides an instant read-out of dose information when connected to a computer via a connector such as a (an)

Medical physicists use ionization chambers connected to electrometers to perform the annual standard measurements required by state,federal,and health care accreditation organizations for radiographic and fluoroscopic devices.These annual measurements include 1) x-ray output in Gy or mGy. 2) fluoroscopic radiation entrance rates in mSv/min. 3) kVp setting accuracy. 4) exposure time exactness. 5) half-value layers,or beam quality

Of the following,which are disadvantages of using pocket ionization chambers as personnel dosimeters? 1) They can discharge if they are subjected to mechanical shock. 2) Because these devices provide no permanent legal record of exposure,health care facilities that use this method to record personnel exposure must delegate someone to keep such a record.3.If not read each day,the dosimeter may give an inaccurate reading because the electric charge tends to escape.

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)

Which of the following instruments generally has a check source of a weak,long-lived radioisotope located on one side of its external surface to verify its constancy daily?

Which of the following is not a requirement that radiation survey instruments must meet?

The optically stimulated luminescence (OSL) dosimeter is "read out" by using a (an)

What do optically stimulated luminescence dosimeters,thermoluminescent dosimeters,pocket ionization chambers,and digital ionization dosimeters have in common?

Three different filters are incorporated into the detector packet of the optically stimulated luminescence dosimeter.Of what are these filters made?

Which of the following personnel dosimeters resembles an ordinary fountain pen externally?

What is the maximum period of time that a thermoluminescent dosimeter (TLD) may be worn as a personnel device?

The front of the white paper packet of the optically stimulated luminescence (OSL) dosimeter

Which component(s) of the Geiger-Muller survey meter alerts the operator to the presence of ionizing radiation?
