which of the following are natural sources of ionizing radiation
Give this one a try later!
radioactive elements in the earth's crust and in the human body
which of the following identifies an element and determines its placement in the
periodic table of elements
Give this one a try later!
atomic number
what is the Z or iodine
,Give this one a try later!
53
exit or image formation radiation is composed of which of the following
Give this one a try later!
non-interacting and small angle scattered photon
Why does a GM tube have a "check source" of a weak, long-lived radioisotope
located on one side of its external surface?
Give this one a try later!
GM tubes tend to lose its calibration over time, the instrument generally has
a "check source" to verify its constancy daily
how does ionizing radiation damage biologic tissue
Give this one a try later!
while penetrating body tissue, ionizing radiation produces biologic damage
primarily by ejecting electrons from the atoms comprising the tissues
Milisievert (mSv)
,Give this one a try later!
a subunit if the sievert equal to 1/1000 of a sievert
made of transparent lead acrylic material impregnated with approximately 30 % lead
by weight
Give this one a try later!
clear lead shields
the milisievert (mSv) is equal to
Give this one a try later!
1/1000 of a sievert
which of the following defines attenuation
Give this one a try later!
absorption and scatter
radioactive elements in the crust of the earth and in the human body may be
classified as
, Give this one a try later!
natural sources of ionizing radiation
total filtration
Give this one a try later!
inherent filtration + added filtration
why should a health care facility have a radiation safety committee
Give this one a try later!
the NRC mandates that a radiation safety committee be established for the
healthcare facility, this provides guidance for the program and facilitates its
ongoing operation
in which of the following x-ray interaction with matter is the energy of the incident
photon completely absorbed
Give this one a try later!
photoelectric
