✔✔the responsibility to adhere to the regulations, license conditions and company
policies falls to - ✔✔the radiographer
✔✔Ernest Rutherford - ✔✔Alpha particles were discovered by?
✔✔Massachusetts General - ✔✔The first medical X ray was conducted at?
✔✔true - ✔✔Regulations from one state to the next are essentially the same for
Radioactive materials
✔✔(RSO) Their program's radiation safety officer - ✔✔A radiographer has several
avenues to seek guidance and counsel. The first person he or she can turn to is?
✔✔Wilhelm Röntgen - ✔✔the origins of industrial radiography can be attributed to?
✔✔particulate and electromagnetic - ✔✔The two basic types of radiation are ?
✔✔at the speed of light with out regard to pressure, temperature or magnetic -
✔✔Wavelike radiation travels at?
✔✔186000 miles/s (299 338 km/s) - ✔✔Gamma rays travel in a wavelike motion at the
speed of light, which is?
✔✔true - ✔✔Matter can be turned into energy ?
✔✔two protons and two neutrons - ✔✔Alpha Particles are much like a helium nucleus
as they have ?
✔✔positive charge - ✔✔Alpha particles have a/an ?
✔✔negative charge - ✔✔Beta particles have a/an?
✔✔much less than that of an alpha particle
As beta particles are essentially highspeed electrons, and electrons are 1/1840 the size
in mass of a proton , it is easy to see how much smaller they are than a proton.
As an alpha particle is two protons and two neutrons , you can imagine how much less
mass a beta particle would have than an alpha particle. - ✔✔Beta particles have a
mass?
, ✔✔they travel at sub-light speeds and as such are easily contained or shielded. - ✔✔in
modern radiography the alpha and the beta particles of little concern because?
✔✔High-voltage direct current across the cathode of vacuum tube - ✔✔X-radiation is
created by applying a?
✔✔passage of electrons across the tube striking the target - ✔✔X-ray are produced by
an X-ray tube by the
✔✔non ionizing radiation - ✔✔Radio Waves, microwaves and infrared waves are types
of ?
✔✔1 AMU
(atomic mass unit)
Protons and neutrons both have mass, each nearly equal and represent 1 atomic mass
unit, while electrons are much smaller at 1/1840 their size. - ✔✔the neutron has an
atomic mass of ?
✔✔primary beams have greater penetrability then secondary beams - ✔✔The shorter
the wavelength or higher the frequency, the greater the penetration; as such?
✔✔Electrons - ✔✔Elementary particles with a unit negative electrical charge and a
mass approximately equal to 1/1840 that of ?
✔✔A= Mass number - ✔✔the atomic weight of an atom is the combination of the total
number of protons and neutrons he'd in the nucleus. this is also know as the ?
✔✔(FALSE)
only alpha and beta particle are affected by magnetic fields because alpha particles
hold a positive charge and beta particles a negative charge. gamma rays and X-ray,
having no physical mass and no charge, cannot be attested by magnetic fields. -
✔✔Gamma rays are affected by magnetic fields? (true or false)?
✔✔(FALSE)
Once an isotope has decayed, theoretically at some point the material would be
completely stable and thus not radioactive. this would be theoretical only as it would
never truly reach absolute zero. - ✔✔As a radioisotope decays, the elements return to a
stable state by undergoing several steps; once complete the material continues to
produce radiation (true or false)?
✔✔The half-life of iridium-192 is essentially 74.3 days, 148 days divided by 74.3 days,
148 days divided by 74.3 is basically 2 or 2 half-lives. - ✔✔after 148 days, Ir-192 would
have undergone how many half lives?
