LSA
LSA stands for Low Specific Activity and is a general term for naturally occurring radioactive materials that may be present in gas and oil processing installations. Traces of naturally radioactive materials have been present in the earth’s crust since it was formed, and are extracted together with gas, oil and especially, water. LSA is found on the insides of installations in the form of scale on the walls, dust between flanges and sludge on the bottom of vats and tanks. Closed installation: LSA is found on the inside and not on the outside. There is therefore no radiation risk on closed installations. For LSA, there is virtually no radiation risks, but there is a risk of (internal) contamination. This risk is especially high if LSA materials are present as dust in the air and may be inhaled. For work involving opened installations, special precautions are taken, such as wearing disposable overalls , boots, gloves and, if necessary, breathing protection. Additionally, when carrying out work involving LSA, there is always a radiation protection expert who provides instruction, supervises activities and makes screening measurements.
