Hi, I have not quite fully understood about the harm due to the ionizing affect of alpha particles in medical physics.
Upon preliminary Google search, I found an article briefly summaries the affect as follow:
1. cell dies
2. cell repairs itself
3. the cell mutates incorrectly and can become cancerous.
However, the author indicated that not all cells are affected by ionizing radiation in the same way.
My prior knowledge is that I understand alpha particle can attract electrons in the atoms shell (i.e., ionising atoms in its path). As the alpha reduces its speed, the ionzing becomes stronger as moment = F x change in time.
My questions are:
(a) What is the ionizing affect got to do with harming the human body?
(b) Does the ionizing affect impact on the DNA?
Look forward to getting a more elaborate explanation.
