GENERIC RADIATION WORKER TRAINING UPDATED ACTUAL
QUESTIONS AND DETAILED ANSWERS GUARANTEED PASS
Describe your ALARA responsibilities
- Practice ALARA concept
- Follow procedures and policies
- Follow all written or verbal instructions from Radiation
Protection
- Know the dose rates in your work area
- Be aware of your current dose
- Comply with administrative and federal dose limit
- Notify Radiation Protection (RP) or your supervisor if you
have suggestions on reducing dose
Define components of ALARA program
- Pre-job ALARA reviews and pre-job briefings
- Job planning to include worker experience and lessons
learned
- Training mockups
- Good radiological work practices such as temporary
shielding
- Engineering controls such as ventilation and system cleanup
Can time reduce dose?
,The more time you spend working around radiation, the more
dose you receive. Work planning and practicing mockups can
greatly reduce the time you spend in a radiation area, thus
reducing dose.
Can distance reduce dose?
Distance between you and radiation source effects dose. Dose
rate decreases as you move farther away from the source. EX:
Moving from 1 foot to 2 feet -> dose rate drops 1/4. 1 foot to 3
feet -> dose rate drops 1/9.
Can shielding reduce dose?
Permanent and temporary shielding in the plant can reduce
the dose you receive by reducing the intensity of a radiation
field. Lead Blankets are often used as shielding b/c they can
shield alpha, beta, and gamma radiation. If dose required to
install lead blanket exceeds the dose savings, it doesn't make
ALARA sense.
Define and calculate Stay Time
Stay Time: is the amount of time you can work in an area
where radiation is present. It is based on your current dose
and the dose rates in the work area.
S.T. = (dose limit - current dose) / dose rate in work area
, State individual responsibilities regarding temporary shielding
Never tamper with, remove, adjust, or modify installed
shielding. RP permission is required before installing,
removing, or moving temporary shielding. Improperly installed
shielding can overload the design weight of the component it is
intended to shield.
State purpose of dosimetry
Dosimetry devices accurately measure the amount of radiation
a person is exposed to. Normally people working around
radiation in a nuclear plant wear two dosimeters.
What is a Primary Dosimeter?
It is the Dose of Legal Record (DLR) and there are two:
- Thermoluminescent Dosimeters (tlds)
- Optically Stimulated Luminescense (OSL)
Describe the DLR
Provides a permanent legal record of your occupational dose.
Measures gamma, neutron, and beta radiation. Can only be
read by RP personnel using special equipment. Has NO audible
alarm.
