Certification of a radiation worker at TAU:

In order to obtain certification as a radiation worker, you must first contact your Faculty Radiation Safety Officer (celeste@tauex.tau.ac.il) and fill out a form for your health fund.

Medical Tests:

The form will be sent to the University Safety Unit, which will provide the worker with referrals for medical tests (blood, urine and eye tests) and an appointment with an occupational safety doctor.

Upon completion of all the required tests, the doctor will issue the worker a health certificate that must be renewed yearly.  Renewal of this certificate is a legal requirement of radiation workers.

Safety Training:

The new radiation worker will undergo general Radiation Safety Training with a certified Radiation Safety Officer in addition to specific training in the laboratory where he will be carrying out the work with radioactive materials/x-ray equipment.  

Yearly Radiation Safety Training refreshers:

Radiation safety training refreshers are a yearly requirement and take the form of on-line tutorials via your account in the Moodle (Mytau) system.  As with the medical tests, yearly safety training is mandated by law.

 

Physical requirements of a Radiation laboratory:

  1. The entrance must be labelled with a “Caution Radioactive Material” sign. Refrigerators, freezers, and containers in which materials are stored or transported must have a visible label with the radiation caution symbol.
  2. Floors must be covered with a nonporous surface such as linoleum.  Ceramic tiles are not allowed.
  3. Benches should be nonporous and easily decontaminated; Alternatively, benches can be covered with a plastic-lined bench cover.
  4. Nonporous walls covered with easily washable paint;
  5. A sink and soap-dispenser that can be turned on/activated with your elbow or automatically.
  6. A high-quality chemical resistance fume hood should be available in the room, that is suitable for work with radioactive vapors, dusts, fumes and gases
  7. Facilities should be available to adequately secure the radioactive materials.

 

 

 

Purchasing radioactive materials:

A researcher who intends to purchase radioactive materials must first make sure there is a room with a radiation permit at his/her disposal.   Workers or students who plan to carry out the experiments must have received proper certification and training.  Upon ordering radioactive materials, chose the following category in the ERP system:

|7.0|122|

כימיקלים, גזים וביולוגיים - חומרים רדיואקטיביים (קבוצת או"ם מס' 7)

 

Security of radioactive materials:

All radioactive materials must be stored in a labeled cabinet/refrigerator/freezer within a room that can be locked.  If the refrigerator/freezer is not in a locked room, a lock can be put directly on the appliance.  Radioactive materials should only be accessible to those certified to use them.

 

Personal Protective Equipment (PPE):

When working with unsealed radioactive materials, PPE must be worn at all times. This includes a lab coat, eye protection and disposable gloves.  Closed-toed shoes that completely cover the foot should be worn.

Dosimetry:

If the radiation safety officer determines that you are at risk of external exposure, a dosimetry badge will be issued to you.  This badge must be worn at all times you are at risk of exposure.

 

Waste:

Radioactive waste should be collected in a labeled container on the bench.  The container should be emptied at the end of the day (or when full) into the large yellow radioactive waste barrels that are collected by the Nahal Soreq radiation center.  Each building in the faculty has one locked room with radioactive waste barrels.  The key can be obtained from the radiation safety officer.

Researchers working with P32 or other low-half-life isotopes can store the waste for 10 half lives and dispose of it with the regular waste.  This must be coordinated with the radiation safety officer.

 

X-ray equipment:

The Faculty of Life Sciences has one open x-ray apparatus that is used for testing diffraction of protein crystals.  Anyone wishing to use this apparatus must go through the full certification procedure, including medical tests and training.  The apparatus is located in a locked room on the ground floor of the Sherman Building.  An additional closed XRF apparatus can be found in the laboratory of Prof. Micha Ilan.  Users of this apparatus are required to undergo radiation safety training for users of x-ray apparatus.

 

Pregnancy and work with radioactive materials:

Women who become pregnant must immediately notify the radiation safety officer as well as their immediate supervisor.  An additional set of medical tests will be carried out after the fourth month of pregnancy.  Radiation levels will be assessed to ensure that the fetus is not exposed to levels beyond those mandated by law. In general, there is no problem to continue working with the small amounts of radioactive materials that are used in the faculty.

 

Transfer of radioactive materials: 

No transfer of any radioactive materials between laboratories either within or outside of the university is permitted without prior coordination with the university radiation safety officers.

Similarly, no transfer of x-ray equipment is allowed without prior approval.

In the event of a spill:

  1. Warn people in the vicinity.
  2. Cordon off the contaminated area.
  3. Report the spill to Radiation Safety 
  4. Treat contaminated personnel first
  5. Clean up the spill yourself and test the area for contamination.
