How Big Are the Largest Black Holes and How Do Astronomers Detect Them? Written by: However, they can still be indirectly detected through their interaction with matter around their boundaries. Protons have special characteristics that allow normal tissues to be .. The most popular idea of Dark Matter we have, is that is made of WIMPs, or Weakly Interacting Massive Particles. For example, gas and dust around a black hole emit X-rays as they spiral inwards. Principles Of Radiation Interaction In Matter And Detection. Astronomers have observed stars in other galaxies orbiting particularly bright regions containing highly concentrated gas and emitting unusually large amounts of radiation. However, the tissue volume that can benefit from this feature may be very small in SRS and the corresponding clinical gain might be difficult to detect. The principles of classical radiobiology are similar for protons and photons even though they differ in terms of physical properties and interaction with matter resulting in different dose distributions. If these really do exist, there would be millions passing through us every second. Some of its properties could be defined already, we obviously couldn't see it, so it didn't interact with electromagnetic radiation (light would simply pass straight through it) but its main property was that it had mass.
