- Limit the height of the product falling into a storage tank or vessel - Limit flow rate - When grounding, connect as much as possible to the existing grounding network - Wear anti-static footwear and clothing - Add anti-static material to the liquid
Safety measures for ionizing radiation - Stay as far away as possible - Avoiding contamination with a radioactive substance by good hygiene and leaving packaging containing radioactive material intact - Cordon off the area around the source - Wear proper PPE - Post warning signs - Perform (permanent) measurements Obligations for employees who work on devices or substances with ionizing radiation - Measuring and monitoring the personal dose of radiation that has been recorded - Undergo medical examination Tasks of the radiation expert that a company must rely on - Monitor radiation safety and hygiene - Check whether employees, tools, equipment or workplace are contaminated - If necessary, prescribe additional measures or stop work
Definition (ionizing radiation) Radiation that is capable of creating
electrically charged particles in the irradiated material (for example the cell structure of the human body) and can therefore change the structure of that material
Definition (radioactive substance) Substance that emits ionizing radiation
Activities and situations involving ionizing radiation - Natural gas extraction, ore processing - Medicine, nursing - Nuclear power plants - Detection devices - Material control - Measuring equipment in the process industry
Non-ionizing radiation Other, less strong radiation than ionizing radiation, unable to create ions
Examples -
Microwaves
- - - - -
Ultraviolet radiation
Sunlight
Laser beams
Definition (natural radioactivity) The spontaneous emission of ionizing radiation by natural substances
Infrared radiation
Radio waves
Safety measures for non-ionizing radiation - Attention to instructions and information on devices - Respect the instructions regarding the duration of use - Respect safety distances
Influencing factors on the level of exposure - Distance to the radiation source - Type of radioactive material - Duration of radiation exposure
