Industrial Radiography Radiation Safety Test Questions and Answers Graded A+
In the early years of radiography, what caused personnel to be overexposed? - Answers Poor equipment
design, lack of understanding, lack of and poor safety practices.
In what year did Marie Curie discover radium? - Answers Late in 1898
Who coined the term radioactivity? - Answers Marie and Pierre Curie
In the early years of radiography from 1920-1930, the maximum thickness that could be inspected via X-
radiation was ___ of steel? - Answers 3 in.
Historically, it has been proven that the predominant cause of overexposures is: - Answers Improper
surveys, the source being left in an uncontrolled state, the source not being locked once retracted to the
shielded position
The responsibility to adhere to the regulations, license conditions and company policies falls to: -
Answers the radiographer
Alpha particles were discovered by: - Answers Ernest Rutherford
The first medical X-ray was conducted at: - Answers Massachusetts General
Regulations from one state to the next are essentially the same for radioactive materials. - Answers true
A radiographer has several avenues to seek guidance and counsel. The first person he or she can turn to
is? - Answers their program's radiation safety officer (RSO)
The origins of industrial radiography can be attributed to: - Answers Wilhelm Röntgen
The two basic types of radiation are: - Answers particulate and electromagnetic
Wavelike radiation travels at: - Answers at the speed of light without regard to pressure, temperature or
magnetic fields
Gamma travel in a wavelike motion at the speed of rays light, which is: - Answers 186 000 miles/s (299
338 km/s)
Matter can be turned into energy. - Answers True
Alpha particles are much like a helium nucleus as they have: - Answers two protons and two neutrons
Alpha particles have a/an: - Answers positive charge
Beta particles have a/an: - Answers Negative charge
Beta particles have a mass: - Answers much less than that of an alpha particle
, In modern radiography the alpha and beta particles are of little concern because: - Answers they travel
at sub-light speeds and as such are easily contained or shielded
X-radiation is created by applying a: - Answers high-voltage direct current across the cathode of a
vacuum tube
X-rays are produced by an X-ray tube by the: - Answers passage of electrons across the tube striking the
target
Radio waves, microwaves and infrared waves are types of: - Answers nonionizing radiation
The neutron has an atomic mass of: - Answers 1 AMU
The shorter the wavelength or higher the frequency, the greater the penetration; as such: - Answers
primary beams have greater penetrability than secondary beams
Elementary particles with a unit negative electrical charge and a mass approximately equal to 1/1840
that of - Answers electrons
The atomic weight of an atom is the combination of the total number of protons and neutrons held in
the nucleus. This is also known as the: - Answers A number
Gamma rays are affected by magnetic fields. - Answers false
As a radioisotope decays, the elements return to a stable state by undergoing several steps; once
complete the material continues to produce radiation. - Answers false
After 148 days, Ir-192 would have undergone how many half lives? - Answers 2
Activation is the process of bombarding material with: - Answers excess neutrons
The total number of ___ identifies an element. - Answers protons
Gamma radiation has a shorter wavelength than visible light, therefore making it: - Answers more
penetrating
Overexposures to personnel can result in: - Answers cancer, genetic defects carried into further
generations, and death
All radiation exposures are equally serious and can result in death. - Answers false
Ionizing radiation passes through the entire body; as such, damage can occur to the: - Answers skin,
internal organs , muscles
Prompt effects of radiation exposure to acute doses include: - Answers blood changes, nausea, fatigue
Industrial radiography, being one of the most dangerous jobs in the world, has killed: - Answers only one
radiographer is known to have died in the world
