TRAINING
REQUIREMENTS
• Initial Training on Radiation Safety.
•
“Radiation Safety Guide for Users of Radiation
Producing Devices”
• RPD or Radiation Source Specific
Training.
•
Given by a RSO approved Trainer
• Annual refresher on Radiation Safety.
4732.0505 Procedures and Safety Instruction
for Facilities.
An individual operating radiation-producing
equipment must have be instructed initially in
facility specific and system specific safe
operating procedures, emergency procedures,
quality control procedures, and the proper
protective shielding to be used. Additional
training must be conducted at the time of any
change to the quality assurance program or
change in radiation output.
RADIATION PROGRAM
AUDITS. 4732.0540
TRAINING
• Is required of all persons who work with
radiation producing devices or radiation sources.
• All workers, student and worker who may be
exposed the radiation are required to complete
annual training.
• The training is done on an academic calendar
schedule.
• Applicability – A quality assurance program
must be done annually.
• Procedures – All audit are performed
according to current established procedures.
• Corrective Action – All issues found during
an audit must be corrected and
documented.
• Records – Audit records are prepared and
maintained by the RSO
SIGNAGE
All areas that contain Radiation Producing
and/or Radioactive material must have signage
to indicate the level activity present. Signage is
available from the RSO.
SIGNAGE LOCATION
Should be posted at each entrance to the lab
and within the work area.
EMPLOYEE
NOTIFICATION
A “Notice to Employees” must be displayed in
all areas that may contain radiation. Available
from RSO.
UNAUTHORIZED
SIGNAGE
Only Areas that contain or may contain
radiation are to have signage. They are not to
be use in any other way. Please report any
misuse of signage.
ALARA
Basic principle to follow whenever working
with radioactive material. All exposures should
be As-Low-As-Reasonably-Achievable.
WORK AREA SURVEYS
Following the use of unsealed sources the work
area must be surveyed for possible
contamination and cleaned as needed.
Exposure
REGULATORY DOSE
LIMITS
Radiation Worker
• Whole body-5rem/yr
• Extremities-50rem/yr
• Skin-50rem/yr
• Organs-50rem/yr
• Lens-15rem/yr
Non Radiation Worker
• Fetus-0.5rem
• Public-0.1/yr
Declared Pregnant Rad
Worker
• Fetus-0.5rem
ACUTE EXPOSURE
Absorption of a relatively large amount of
radiation over a short period of time. Seen in
early radiologists, atomic bomb survivors,
people near Chernobyl and certain medical
treatments.
CHRONIC EXPOSURE
Absorption of radiation over a long period of
time.
LAB SECURITY
Make sure your lab is locked at all times when
no one is present. If the area is a shared space
than all persons using that space must have
Radiation Safety Training.
Persons must be present when operating RPD.
BASIC PROTECTION
GUIDELINES
•
•
•
•
Time-limit your time around radiation.
Distance-stay as far away as possible.
Shielding-use shielding whenever possible.
Do not modify or disable any device safety
features.
