How to Work Safely Around Hazardous Materials
This 3 minutes safety training video covers: What is radiation, what are the radiation safety measures in the workplace, what are the different types of radiation, what is the most common route of exposure to hazardous materials, how hazardous chemicals enter the human body, what are the first aid procedures for hazardous chemical exposure.
Most of the radiation we received about 82% is from natural resources, the other 18% comes from man made sources such as x-rays and radiations use for therapy, a small portion of that amount is made up of radiation from power generation. Some exposures may cause little or no problem while others can cause cell damage, alteration of cell DNA causing cell death or mutation. Acute effects a large doses of ionizing radiation includes skin redness and irritation, nausea, vomiting, diarrhea, weakness and even death. Chronic effects can include cancer, pre-cancerous lesions, tumors, cataracts, skin changes and shortening of lifespan. The extensive damage depends on the amount of energy absorb, time period and rate of exposure as well as organs exposed.
