Radiation Protection Module 3 Personnel Monitoring
what is the dose limit for per month of embryo and fetus
0.5 mSv
what is the dose limit for annual frequent exposure for the general public
1 mSv
what is the dose limit for lens of eye for the general public
15 mSv
what is the dose limit for lens of the eye for occupational exposure
150 mSv
what time period was skin erythema used
1900-1930
what year was tolerant dose established
1950
what year did the ICRP recommend the reduction of the annual EfD limit for occupationally exposed persons from 50mSv to 20mSv per year
1991
when did effective dose term start
1991
what is the dose limit for annual infrequent exposure for the general public
5 mSv
how low does the TDL measure
5 mrem
what is the dose limit for total gestation for embryo and fetus
5.0 mSv
what is the annual dose limit for occupational exposure
50 mSv
what is the dose limit for local area of skin hands and feet for the general public
50 mSv
what is the dose limit for local area of skin hands and feet
500 mSv
what does LDE mean
Exposure recorded at the lens of the eye
what is LDE
Lens dose equivalent
what is OSL
Optically stimulated Luminescent
what is OSLD
Optically stimulated Luminescent dosimeter
what is TDL
Thermoluminescent Dosimeter
when a procedure requires the hands of a radiation worker to be near the primary beam the equivalent dose to the hands of that individual may be determined through the use of
a TLD ring dosimeter worn on the hand of the radiation worker
where do you put your personnel dosimetry
anterior surface of the body at collar level outside of protective apparel
where do you put a embryo fetus monitor
at waist level to measure equivalent dose to embryo fetus during gestation
why is it important to know occupational radiation exposure
because we are the occupational dose person being monitored
what are types of TDL badge
body and ring
when a protective apron is not being worn the primary personnel dosimeter should be attached to the clothing on the front of the body at
collar level to approximate the location of maximal radiation dose to the thyroid and the head and neck
What is CEDE
committed effective dose equivalent
what is DDE
deep dose equivalent
what does the NRC do
determines how the ICRP recommendations are incorporated into the US radiation protection criteria
What is a pocket ionization chamber
dosimeter worn in the pocket provides a immediate reading of their exposure
what are the disadvantages of TDL
expensive can only be read once and the info is erased before being used again
what does EDE mean
exposure recorded at the lens of the eye
what does SDE mean
external exposure of the skin or extremity at a tissie depth of 0.007 cm
what does DDE mean
external whole body exposure at a tissue depth of 1cm
what is EDE
eye dose equivalent
how would radiation dose to the abdomen of a pregnant radiographer be monitored during gestation
from a second radiation monitor worn at the abdominal level
advantages of Pocket ionization chamber
immediate reading
what does CEDE mean
internal exposure
which monitors are more sensitive
internal monitors
what instrument is used to calibrate radiographic and fluoroscopic x-ray equipment
ionization chamber with electrometer
what is a control badge
kept behind the lead wall in control room to track exposure to make sure no exposure is happening in the control room and if it is more than zero that means it was exposed.
which chemical compounds functions as the sensing material in a thermoluminescent ring dosimeter
lithium fluoride
what crystals does the TDL contain
lithium fluoride crystals
what is report 102
makes recommendations on equipment design and protection regarding lead shielding and fluoroscopic and mobile exposure rates
what is report 116
makes recommendations pertaining to risk benefit analysis of radiation exposure defines annual exposure limits
what is a digital ionization dosimeter
new device provides immediate measurement size of flash drive provides long term tracking
is the TDL affected by temp and humidity
no
Is the ICRP an enforcement agency?
no its a recommendation agency they gather info from the BEIR and the UNSCEAR but each nation must develop and enforce its own requirements
Is the NRC a enforcement agency
no they leave it up to the state and federal legislation
Disadvantages of OSLD and OSL
reading the results takes a long time
what is the purpose of accumulated dose
records all doses made by an individual for their employer
what is SDE
shallow dose equivalent
what does TEDE mean
the sum of external DDE and internal CEDE exposure
what is TEDE
total effective dose equivalent
what are the advantages of the TDL
unaffected by temp and humidity
advantages of OSLD and OSL
unaffected by temp and humidity and it can be reanalyzed multiple times
What does M mean
you don't have a level or is minimal
