This is very important since the energy released from radionuclides can be evaluated differently by various counting machines. Counting a known amount of activity helps you determine what percentage of an unknown sample you are detecting. This means that your activities in your wipe samples will calculate slightly higher than they actually are. But it is better than using no standard at all. It is always a good idea to identify these projects as they occur and keep in mind that the College is going to great measures to ensure that the highest standards of safety are being met for the removal process.
Asbestos is a naturally-occurring mineral fiber that is mined from rock.
In the past, it was widely used for its unique fireproofing, insulation, and soundproofing qualities. The use of asbestos for these purposes was later prohibited when the scientific community discovered that the fibers were responsible for serious health problems among people who worked directly with its installation or removal. Because many of the buildings around campus were constructed long ago, some of the materials used for their construction still contain asbestos. Existing asbestos in the buildings should not be a cause for concern because asbestos only has the potential to do harm if it is disturbed. If a disturbance such as cutting or breaking of the asbestos occurs, the small fibers may become airborne, increasing the possibility that the asbestos will be inhaled.
