Radioactive pollution can have severe effects on our skin if it is not looked at. It affects us by giving us Skin Cancer and Ulcers. Skin Cancer is the most common type of skin cancer. It is also known as Non - Melanoma cancer. It occurs because of exposure to the sun, tanning booths and ultraviolet radiation. We also get Ulcers on our skin. Ulcers are sores that either occur on the skin or on the mucus membrane, this is accompanied by tissue separation and formation of pus. You can tell its a Ulcer because it appears as a inflammed area around the skin with a reddish color. 


Ulcer (skin):  It is a open sore on the skin or mucus membrane normally characterized by pus or tissue separation. 

Pus: It is a fluid product as a result of inflammation, it is normally a yellowish- whitish color.
