As radiation kills cells by inhibiting their ability to divide, its effects in human beings occur primarily in tissues with high cell turnover or renewal rates characterized by a large amount of proliferative activity. These include tissues such as the bone marrow and the mucosal lining of the stomach and small intestine.
8 Ιαν 2016 · The chapter on whole body radiation treats the effects of decreased white blood cells following radiation exposure more completely. Most of the long term, late effects on tissues and organs are the result of injury to blood vessels, especially to those making up the microvasculature.
25 Οκτ 2010 · Interactions of Radiation with Cellular Constituents. Gamma rays or x-rays interact with atoms in the cell by the photoelectric effect, Compton scattering, or pair production. In human tissue, Compton scattering is the most likely interaction.
The early effects of radiation on these organs result largely from the destruction of the progenitor cells and the consequent interference with the replacement of the mature cells, a process essential for the maintenance of normal tissue structure and function.
5 Απρ 2023 · This chapter describes the deleterious effects of radiation in humans causing cancer and genetic defects that result from DNA and chromosome damage by radiation. A brief description of cell structure and cell growth is given.
10 Ιουλ 2022 · The effects of ionizing radiation on the human body depend on several factors, such as the nature of the effect and the timing after exposure. Biological effects due to exposure to ionizing radiation are variable and inconsistent.
18 Μαΐ 2024 · Mechanistic understanding of biological effects at molecular, cellular and systems levels at various exposure scenarios such as different types of radiation, dose rates and range of doses will help to address some of the underlying myths of radiation effects.
