Terra / BTX uses X-rays to produce the desired X-ray diffraction pattern or X-ray fluorescence spectrum. These X-rays are produced from:
- A radioactive isotope within the instrument
- A gamma ray neutron source within the instrument
- An X-ray tube operating at 30Kv
- None of the above

About This Quiz

This examination will cover areas of radiation safety and proper operation of the inXitu Terra field portable XRD/XRF instrument or the inXitu BTX bencthop XRD/XRF instrument. The questions are drawn from the User's guide.

Terra / Btx Radiation Safety Exam - Quiz

2.

Radiation which has sufficient energy to remove electrons from atoms in materials through which the radiation passes is called ionizing radiation. Examples of ionizing radiation include all but:
- Alpha particle radiation
- Neutrons
- X-rays
- Radio waves
Correct Answer

A. Radio waves

Explanation

Ionizing radiation refers to radiation that is capable of removing electrons from atoms. This process can cause damage to living cells and genetic material. Alpha particle radiation, neutrons, and x-rays all have sufficient energy to ionize atoms and are therefore considered ionizing radiation. However, radio waves do not have enough energy to remove electrons from atoms and are therefore not considered ionizing radiation.

3.

The damaging effects of radiation depend not only on its intensity and duration, but also the type of radiation. For instance, 1 millicurie of tritium a centimeter from the body poses a much different hazard than 1 millicurie of phosphorus-32 a centimeter from the body. Consequently, it is often preferable to measure radiation by describing the effect of that radiation on the materials through which it passes. The units for biological effects of radiation are:
- Exposure
- Absorbed Dose
- Dose Equivalent
- REM/Sievert
Correct Answer

A. REM/Sievert

Explanation

The correct answer is REM/Sievert because REM (Roentgen Equivalent Man) and Sievert are units used to measure the biological effects of radiation. REM is used in the United States, while Sievert is used in the International System of Units (SI). Both units take into account the type and energy of radiation, as well as the effect it has on living tissue. These units provide a standardized way to quantify the potential harm of radiation exposure.

4.

The amount of radiation exposure allowable is defined by the international commission on radiological protection (ICRP).
- True
- False
Correct Answer

A. True

Explanation

The explanation for the given correct answer is that the International Commission on Radiological Protection (ICRP) indeed defines the amount of radiation exposure that is considered allowable. This organization sets guidelines and standards to protect individuals from the harmful effects of radiation exposure, based on scientific research and consensus. These guidelines help ensure that radiation doses received by individuals, whether from medical procedures or occupational exposure, are kept within safe limits to minimize potential health risks.

Rate this question:
5.

The fundamental principle in radiation protection is that all radiation exposures should be maintained as low as reasonably achievable. This is referred to as the ALARA principle. The three key factors which influence an individual's radiation dose from a given source are (check all that apply):
- Time
- Distance
- Shielding
- Magnetics
Correct Answer(s)

A. Time
A. Distance
A. Shielding

Explanation

The ALARA principle states that radiation exposures should be kept as low as reasonably achievable. In order to minimize radiation dose from a given source, three key factors come into play: time, distance, and shielding. By reducing the amount of time spent near the radiation source, increasing the distance between oneself and the source, and using appropriate shielding materials, the radiation dose can be minimized. Magnetics, on the other hand, do not have a direct influence on an individual's radiation dose and are not relevant to the ALARA principle.

6.

Radiation control for instruments, such as Terra / BTX is controlled by the US Federal government for instruments operated in the United States.
- True
- False
Correct Answer

A. False

Explanation

The statement is false because radiation control for instruments like Terra/BTX is not solely controlled by the US Federal government. While the government does have regulations and guidelines in place, there are also other organizations and agencies involved in radiation control, such as the Nuclear Regulatory Commission and the Environmental Protection Agency. Additionally, individual states may have their own regulations regarding radiation control for instruments operated within their jurisdiction.

Rate this question:
7.

It is not necessary to contact your local radiation protection control authority (State, Federal, etc) in order to operate your Terra or BTX.
- True
- False
Correct Answer

A. False

Explanation

The statement is false because it is necessary to contact the local radiation protection control authority in order to operate Terra or BTX. These devices are likely to emit radiation, and therefore, it is important to follow the regulations and guidelines set by the authority to ensure safety. Failing to do so may result in legal consequences and potential harm to individuals and the environment.

Rate this question:
8.

Terra / BTX when operated properly does not produce measurable radiation on any external surface of the instrument.
- True
- False
Correct Answer

A. True

Explanation

When Terra / BTX is operated properly, it does not emit any detectable radiation on its external surface. This means that there is no radiation leakage or emission that can be measured outside of the instrument. Therefore, the statement "True" is correct.

Rate this question:
9.

Terra / BTX feature multiple interlock circuits, which prevent the possible operation of the X-ray generating source when these interlocks are activated.
- True
- False
Correct Answer

A. True

Explanation

The statement is true because Terra/BTX feature multiple interlock circuits. These circuits are designed to prevent the X-ray generating source from being operated when the interlocks are activated. This ensures safety by preventing any potential hazards or accidents that could occur if the X-ray generating source is operated when it shouldn't be.

Rate this question:
10.

Should an interlock circuit activate, an amber light will display on the main instrument panel.
- True
- False
Correct Answer

A. True

Explanation

If an interlock circuit activates, it means that a safety mechanism has been triggered. In this case, when the interlock circuit activates, an amber light will be displayed on the main instrument panel. This indicates that there is a potential issue or problem that needs attention. Therefore, the statement is true.

Rate this question:
11.

InXitu expects that the operator will need to remove the acess panel in order to properly use the instrument. That is, the instrument has user-serviced parts inside.
- True
- False
Correct Answer

A. False

Explanation

The explanation for the given correct answer (False) is that inXitu does not expect the operator to remove the access panel in order to use the instrument. This implies that the instrument does not have user-serviced parts inside.

Rate this question:
12.

Terra / BTX has the ability to perform the following experiments except:
- X-ray Diffraction
- X-ray Fluorescence
- X-ray Time of Flight
Correct Answer

A. X-ray Time of Flight

Explanation

Terra / BTX is capable of performing X-ray Diffraction and X-ray Fluorescence experiments, but it does not have the ability to perform X-ray Time of Flight experiments.

Rate this question:
13.

Terra / BTX have been designed such that proper operation will not result in any radiation exposure.
- True
- False
Correct Answer

A. True

Explanation

The statement suggests that the design of Terra / BTX ensures that proper operation will not lead to any radiation exposure. This implies that the equipment has been carefully engineered and built to prevent any leaks or emissions of radiation during its operation. Therefore, the correct answer is True.
