Especially gamma-ray, the most energetic radiation, is produced by the hottest regions of the universe, violent events as a supernova explosion, and even destruction of atoms. ]]> 2021-01-08 06:00:07 UTC https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066094151 winniehsieh1 https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066099863 Gamma-rays travel a great distance through the air or other material and even can pass through living things like human tissues or inside the cell. That will be much possible that gamma-rays will damage our body health by influencing the construction of the bodies or event changing or effecting on human’s DNA. Ionizing radiation is radiation that can remove electrons from an atom and can be in the form of a wave, like gamma rays or X-rays. Gamma-rays can pass through the cell directly and will prevent the DNA from replicating correctly in three ways:  first, Changing the chasmal structure of the bases. and then breaking the sugar-phosphate backbone, and the last one will be breaking the H bonds connecting the case pairs. And further, these three ways will lead to DNA lesions and DNA mutations. All in all, it means that gamma-ray can get into human's cell, and destroy our DNA. When DNA gets destroy, then the cell is no longer be used. So, if a person get close to gamma-ray, and it destroys his DNA, then the person may die. ]]> 2021-01-08 06:06:36 UTC https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066099863 winniehsieh1 https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066115101

Probably, there will be more variable human diseases happening under the exposure of gamma-rays. Gamma-rays may cause cancer, because how cancer comes is that, cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes in DNA.]]> 2021-01-08 06:55:35 UTC https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066148980 winniehsieh1 https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066155330 2021-01-08 07:02:03 UTC https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066155330 winniehsieh1 https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066158146 2021-01-08 07:04:29 UTC https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066158146 winniehsieh1 https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066158679 2021-01-08 07:05:00 UTC https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066158679 winniehsieh1 https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066160367 2021-01-08 07:05:59 UTC https://padlet.com/winniehsieh1/xq6v1a56kjq6orbj/wish/1066160367
