Title: Radiation Safety Training Annual Refresher Training Washington State University Radiation Safety Office
1 Radiation Safety TrainingAnnual Refresher
Training Washington State UniversityRadiation
Safety Office
2Why have refresher training?
- The annual refresher training is designed to
reinforce important safety information, provide
any new information and to cover areas that have
presented problems in laboratories over the past
year.
3In each laboratory that is authorized for
radioactive materials use, you will find this
form (RHF-3) posted. This form gives the
contact information for the Washington state
Department of Health. It also list some of your
and some of the employer's responsibilities.
4Good Laboratory Practices
- Remember Time, Distance, Shielding
- Wear Protective Clothing gloves, lab coat, long
pants, - full toed shoes
- Designate areas for RAM work
- Cover work areas with absorbent paper, absorbent
side up - Use a hood if possible
- Avoid skin contact with contaminated gloves
- Survey your gloves, hands, coat, shoes, and your
work area - Always wash your hands (even when wearing gloves)
after the experiment, as well as before leaving
the work area, picking up the phone, etc.
5CONTROLLING EXTERNAL HAZARD
- TIME Radiation dose is proportional to the
- duration of the exposure.
- DISTANCE Radiation dose is proportional
to 1/(Distance)2. - SHIELDING Radiation dose is determined by
- the type and thickness of shielding materials
used. - Correct selection of Shielding Materials
- are a function of type and energy of radiation.
6Protective Clothing
- Can be a very effective means of preventing skin,
eyes, clothing from becoming contaminated - Always wear Gloves (may want double layer)
- Always wear your Lab Coat
- Eyewear to prevent splashes and provide
- shielding for high energy beta emitters
- Closed toe footwear and long pants are required
- It is much easier to remove contaminated clothing
than to decontaminate your skin!
7 Contamination Control
- The major hazard for most radioactive materials
on the WSU campus comes from internalizing the
radioactive material. - Once the radioactive materials are inside your
body, you lose all the protections from TIME,
DISTANCE AND SHIELDING. - Contamination Control is the key to preventing
internalization of radioactive materials.
8Contamination Control
- Watch out where you put your hot
- hands during an experiment
- Monitor yourself and your work area
- frequently for radioactivity (gloves, hands,
feet, etc.) - Use most sensitive scale on meter (X0.1 or X1)
and have the sound on - Have meter out and handy
- Make sure to wash your hands frequently and after
finishing an experiment Dont bring radioactive
material to lunch or to your home! - Monitor your work area before and after an
experiment
9Surveys
- After each use of radioactive material Except
H-3, the area shall be surveyed using an
appropriate survey meter (not required to be
documented) - Including the use of H-3, all areas of
experimental use shall be wipe tested to
determine if contamination is present (not
required to be documented) - Documented surveys (meter and wipe test) must be
completed on either a weekly or monthly basis
depending upon the isotope and frequency of use.
10Survey meter use.
- Use of Survey Meter review.
- Check for Calibration Sticker
- Check battery
- Check background radiation
- Check meter response to a known
- radiation source.
- Record the check source results and
- background readings in the meter notebook.
11Radiation Safety Instrumentation.
- Before an instrument is used for a radiation
safety survey. It must be determined that the
instrument is functioning properly and that it is
calibrated. This includes both radiation survey
meters and LSCs. By using the quality assurance
notebooks associated with the instrument. You can
determine if the instrument is - functioning
properly - and calibrated.
12Survey meter Quality Assurance Notebook.
Every survey meter should have a Survey Meter
Quality Assurance Notebook.
Be sure the cover page of your note book is
filled in properly.
Fill in meter manufacturer and serial number.
Fill in probe model number and serial number.

radiation safety survey.
15LSC Quality Assurance notebook.
- Each LSC will have a Quality Assurance Notebook.
- Be sure to fill in the cover of the notebook.
- Supervisory Authorized user or
- equipment coordinator. Plus an
- alternate and their contact
- information.

Check to see when the last SNC or IPA was run.
This is a self check of the LSC. It is done by
counting the unquenched standards that came with
the LSC. The printout should be in the back of
the notebook. It must have been done within the
past 7 days.
You are now ready to start counting your swipes.
Be sure the information at the top of the page is
filled in.
Fill in the date and your name.
Enter the number of the program you are using to
count your swipes.
Check the calibration status of the LSC. This
information is in the back of the notebook. The
LSC must have been calibrated within the past 12
months.
This is the data page inside the notebook.

immediate control of the licensee.
The authorized user must Maintain security of
radioactive materials or radiation machines under
his or her control or possession.
19Security and control
- Radioactive materials must be secured.
- Either by locking the lab door when
- the lab is unattended or by placing the
- radioactive materials in a lock box or in
- a locking freezer or refrigerator.
- DO NOT LEAVE RADIOACTIVE MATERIALS UNATTENDED.
20Radioactive materials inventory control.
- WAC 246-220-020
- Records.
- (1) Each licensee or registrant shall maintain
records relating to the receipt, use, storage,

- A large part of inventory control is proper waste
tracking and reporting. The use log is very
important for proper waste reporting.
23Waste Program
