RADIATION ONCOLOGY

 Biological effects of Non ionizing radiation Non-ionizing radiation can define lower-range frequency waves in the electromagnetic range, and travel in space with the power of oscillating electric and magnetic fields. The difference between ionizing and non-ionization is, non-ionizing radiation energy is too low to process the ionizing process which expels electrons from the coulomb attraction of the nucleus. But it can transfer an electron from a low-energy state to a high-energy state. This excitation process can be induced risk to health by non-ionizing radiation. According to the energy of photons, different types of non-ionizing radiation energy decrease from ultraviolet radiation to radio waves.   Copyrights:  https://www.osha.gov/radiation   Ultraviolet radiation (UV) has a shorter wavelength than light and longer than X-rays. When certain cells are exposed to UV radiation the damage is induced by both photochemical and heating reactions. Photochemical e...

 Cellular Response for Ionizing Radiation Radiation sources are all around the environment and every time we are exposed to different kinds of radiation from low-frequency to high-frequency electromagnetic range. Studies of radiation mainly use for radiotherapy and space exploration. Biologically cells respond to radiation depending on their energy. When we consider radiotherapy it exposed cells intentionally and damages cell structures which cell harmful to the body with various mutations called tumors. Progress of this treatment depends on the radioresistance of tumor cells and induced damage to normal cells located near to tumor. Increasing radiodensities of tumor cells and specific radioprotection of normal tissues are strategies used to decrease the amount of damage to normal cells in radiotherapy, in a Space environment definitely produce highly protective fabrics and covers to reduce endanger of astronauts from cosmic radiation.  As mentioned in my previous blog q...

                                                  Radiation sources in Cosmic Environment  Radiation is defined as emission energy as electromagnetic waves or as moving subatomic particles such as moving neutrons, protons, electrons, neutrino, photons etc. Basically, radiation can divide into two types which are called ionizing radiation and non-ionizing radiation. When Ionizing radiation pass through the matter it can remove electrons from atoms, molecules including living tissues and produce ions for a example x rays, γ rays, α particles, βparticles and positrons but non ionizing radiation dos not have energy to remove electrons but have energy to molecules and sub atomic particles move in an atom but it cannot remove electrons for a examples Ultra violet radiation, Infrared radiation, microwaves, radiofrequency Radiation can also divide into two types acco...

                                                                                                    NASA Contributions to Cancer Research   NASA (National Aeronautics and Space Administration) was established on Oct 1, 1958, as an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and discovering secrets of the universe. NASA is funded by taxpayers who are citizens of the United States of America. NASA accelerated the works already human and robotic spaceflights. NASA began its marvelous journey with project Mercury (1958) then project Gemini, Six successful human moon landings (Apollo program 1961 - 1972), Mars Lander missions, Planetary flybys, and many more. But NASA not o...
