A cobalt supply has decayed from its unique activity after 3 half-lives. Originally it turned into 88
Ci (3256 GBq). Its contemporary hobby is: - ANS-eleven Ci (407 GBq)
A cobalt supply of seventy three Ci is exposed for a full 60 min. Assume a 14.Zero R/Ci aspect,
taking pictures via a
3 half of-fee collimator. What could the constrained location be at the cold or collimated facet of
the collimator? - ANS-253 ft (77.44 m)
A manipulate panel in an X-ray gadget must have sincerely seen which of the following
statements? - ANS-caution: X-rays produced when energized
A declared pregnant radiographer or assistant may acquire no greater than ________ for the
entire pregnancy. - ANS-500 mR (5000 μSv)
A direct reading ionization chamber, together with a dosimeter, has the advantage of supplying
an: - ANS-on the spot dose records seeing that ultimate time charged
a dosimeter - ANS-dose charge
A dosimeter should be able to reading a number of: - ANS-0-200 mR (zero-2 mSv)
A film badge/TLD information what? - ANS-overall dose records for the period worn
A high radiation location is defined as "a place reachable to people, in which they may get hold
of ..." - ANS-one hundred mR/h (1000 μSv/h)
A leak check could be considered failed ought to the sample tested go back a cost greater than:
- ANS-zero.0.5 μCi (185 Bq)
A member of the public or unmonitored person is allowed to get hold of up to, but now not to
exceed: - ANS-2 mR/h, 100 mR/year
(20 μSv/h, one thousand μSv/year)
, A monitored man or woman may receive up to 5000 mR (50 000 μSv) in keeping with 12
months. What could be considered an excessive amount of radiation exposure to that
individual? - ANS-any useless exposure to radiation
A non-declared pregnant radiographer or assistant may additionally receive no more than: -
ANS-5 R according to year (50 mSv)
A radiation place is defined as "an area handy to individuals, in which they could get hold of ..." -
ANS-5 mR/h (50 11Sv/h)
A radiographer and assistant are standing in a 2 mR/h (20 μSv/h) field. What would the
assistant's total dose be after 4 h? - ANS-eight.0 mR (80 μSv)
A radiographer has several avenues to are seeking guidance and suggest. The first character
he or she will be able to turn to is? - ANS-their application's radiation safety officer (RSO)
A radiographer is receiving one hundred mR (1000 μSv) on the crank assembly. The crank
assembly is 25 feet (7.62 m) in period. Where might the "RADIATION AREA'' sign be published?
- ANS-111.8 feet (34.08 m)
A radiographer is receiving one hundred mR/h (one thousand μSv/h) at the crank assembly. The
crank meeting is 25 toes (7.62 m) in duration. How long will it take for the radiographer to
acquire a complete dose of 50 mR (500 11Sv)? - ANS-30 min
A radiographer reads 7.Five on the lOx scale of the survey meter. What is the modern dose rate
at that role? - ANS-seventy five mR/h
A radiographer's survey meter is displaying 0 near the supply; it could accurately be assumed
that: - ANS-the meter is in an inoperable state; the radiographer ought to retreat from the supply
till an operational meter has replaced the suspect meter
A price alarm meter or alarming charge meter need to sound a
non-stop audible alarm greater than 80 dL
(0.3 m) at: - ANS-500 mR/h (5000 μSv/h)
A constrained vicinity is described as an area: - ANS-to which access is confined for the reason
of controlling radiation publicity
A sealed source emits what? - ANS-gamma rays
A transport container is surveyed and discovered to be 3 mR/h at 39.37 in. (30 11Sv/h at 1 m).
What label might be required? - ANS-Yellow III
