Safety Rules in Radio Chemistry
before the studen start the lab they should have completed the following:
- Answered question sheet with repetition questions. Delivered this before the laboratory excersise starts.
- read, understand and signed a safety protocol for working in a Radio chemistry laboratory
=====safety rules =====
In the laboratory there is measurement instrument to be used to check the amount of radioactivity and where it is. Hence you can verify that neither you nor your fellow students are irridated by dangerous rays.
For pregnant there are specially strict rules for the level of exposure. The amount of activety in these exerciser are so small that they are far bellow the safety limit. If you want more information about the safety ask the lab-assistant
ALARA (As Low As Reasonably Possible) principle should be followd at any times. No person should be exposed to more radiation than needed. Therefore all work done with radioactivity should be done meticulous and planned in advance. Mistakes or carelessness could easily contaminate yourself or persons around you. To avoid this equipment that has been in contact with activity separated from equipment that is not contaminated.
When planing the exercise one should always think about the precautions one must use so that no active material is spread. Therefore certain rules must be followed:
- special lab-coat (not your own) shall bee used during all work in the laboratory and it shall not be taken out of the laboratory
- There shall be no eating or smoking in the laboratory, this includes gum or pastills.
- Only needed papers and writing material shall be taken into the laboratory.
- Purses and other personal effects shall be put in the wardrobe.
- Before a exercise starts all the all equipment needed must be at the work-station.
- A exercise shall first be done with material that is not active so there will be no sudden surprises with activity.
- Gloves and glasses must be used when there is danger of contamination and spilling, control measurements of the gloves must be done before they are removed.
- all exercise with radioactive material shall be done on a plate of plastic with high edges with absorbing paper in the bottom.
- Control on regular intervals that there is no unnecessary spreading of active material, measure gloves and equipment during the exercise.
- Tell the counsellor of any accident leading to contamination of persons, equipment or environment.
- All solid active waste shall be put in special marked plastic jars. Glass and metal shall not be mixed with paper and plastic. Solutes are poured in designated containers. Flammable organic liquids are to be kept separated from aquatic liquids. Radioactive solutes shall not, under any circumstances be poured uncontrolled into the sink.
- when a exercise is done the clean the work-station. Clean all the equipment and control it for contamination, so that it is ready for further use. All active material shall, before they are removed, get marked and eventually get shilded.
- When leaving the laboratory, hands must be washed. If the activity is high a hand/fott monitor should be present so that it is possible to measure for contamination.
