The exposure of radiation could modify the DNA within the cell. The destruction or death to a cell may stem from alterations in somatic cells and takes place in the organism in which the alteration occurred and are named somatic or non-heritable outcomes. Cancer is the greatest significant long-term somatic outcome. Efforts have been formed to evaluate the involvement of ionizing radiation to human alteration frequency by examining generations of exposed and non- exposed Japanese atomic bomb survivors. These evaluations were created on associations of the frequency of several congenital defects and cancers among exposed and non-exposed survivors (HSS, n.d.). Conclusion There are two types of ionizing radiation, direct action, and indirect action and they both have different outcome when they interact with DNA atoms or molecules. Ionizing radiation forces an electron from its orbit surrounding an atomic nucleus, initiating the structure of electrical charges on atoms or molecules. If this electron derives from the DNA itself or from an adjacent molecule and exactly hits and disturbs the DNA molecule, the result is referred to as direct action . There are many concerns in reference to x-rays and the radiation they produce and how it affects an individual’s atoms or molecules have been a topic for years, but it is projected that about two- thirds of the harm produced by x-rays are caused to indirect action. This happens when the electron does not exactly hit the DNA, but hits a common water molecule.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
