especially for the people in Europe who lived through the Chernobyl disaster experienced Germ- line and somatic mutations because of the radioactive chemicals that were release. In responding to the question of what happens to the DNA, cells, and organs after low and high doses of radiation, the nuclear energy agency article on the health impacts of the Chernobyl disaster states that after low dose exposure will cause change multiple things in the germline DNA. During the time of the Chernobyl disaster it was stated “ highest exposure group of those who were acutely exposed (6-16 Gy), the first reaction was usually vomiting, occurring within 15-30 minutes of exposure. These patients were desperately ill; fever and intoxication as well as diarrhea and vomiting, were prominent features. Mucous membranes were severely affected, becoming swollen, dry and ulcerated, making breathing and swallowing extremely painful and difficult. Extensive burns both thermal and due to beta radiation often complicated the illness” (Nuclear Energy Agency, Chapter 5). This shows how fast the radiation affects the cells and organs in the body when exposed to a harmful environment. Another fact to back up the pervious sentence in this chapter it was stated that 499 people were admitted for observation and 231 of those were initially diagnosed from acute radiation syndrome.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
