Glove Box and Decondamination for Industrial workers-Health maintanance

Glove box

This is an enclosure with its own air supply, exhaust system, and lighting which allows some industrial operations on radioactive materials to be carried on directly, instead of with remote-control devices. Bioassay: This is an analysis of breath and urine which determines the amount of radioactivity absorbed by the body. Two or three assays a year are recommended. Instrumentation: Human senses cannot detect radioactivity but special instruments are available which can detect, measure, and record different types of radiation.

Decontamination

 If an accident occurs-if radioactive substances are spilled or if an exhaust system breaks down-properly trained safety personnel can deal with the situation quickly. Their job includes getting rid of the contaminant at once; getting affected workers, their clothing and equipment clean; and testing workers for physical reactions. In addition to causing cancer or leukemia (malignancy of the bone marrow), radiation can do other damage? It can have harmful effects on the skin, including "burns," loss of hair and fingernails, darkening of the' skin. It can affect organs producing blood, thus leading to anemia and insufficient white cells to combat infection. It can lead to hemorrhages-bleeding from gums, in stools, and under the skin-by affecting certain substances that play a role in normal blood clotting.


It can produce sterility in both sexes. Such effects do not usually become manifest until sometime after exposure. In some cases-development of cancer, for example-they may not appear for years. Therefore, very great precautions must be taken, since there is no warning of danger by immediate symptoms such as pain.
