Radiation Protection (Prelim Exam) with
Complete Solutions
isotope same number of protons, different number of neutrons and atomic mass
passive radon meters measures radon concentrated in buildings
has to wait for 3 months for the result
device that is placed within buildings for a 3 month period
radon sump the simplest approach to reduce radon concentrations
used to vent the gas outside the building
sump a pipe connecting a space under a solid floor to the outside
naturally occuring radioactive materials (NORM)
manmade radiation exposure sources of human exposure
diagnostic radiology
radiotherapy
,radioisotopes in nucmed
radioactive waste
fallout from nuclear weapon tests
occupational exposures to radiation other sources of human exposure
diagnostic radiology 90% of total exposure of the population from man made sources of
ionizing radiation
bone marrow
colon
gonads
fetus regions of the body that we are most concerned of in diagnostic radiology
bone marrow the site of hematopoiesis (blood production)
irradiation to this region can lead to leukemia
colon rapid cellular regeneration
gonads testes and ovaries
possibility of heritable damage
, fetus possibility of physical/mental damage to the unborn child
-to ensure radiation safety
-apply radiation protection what is the responsibilities of radtechs
radiation protection effective measures employed by radiation workers to safeguard
patients, personnel, and the general public from unnecessary exposure to ionizing radiation
cosmic radiation
primordial radiation/terrestrial radiation 2 main types of natural sources of background
radiation
cosmic radiation Radiation that comes from the sun and beyond the solar system.
particulate and electromagnetic radiation emitted by the sun and from other heavenly bodies
depends on the altitude
primordial/terrestrial radiation results from deposits of uranium and thorium and their
daughter products
dose rate depends on geographic location
