Alpha particles astronomy is a lecture from the radiation astronomy department that is under development for possible inclusion in the course on the principles of radiation astronomy. You are free to take this quiz based on alpha particle astronomy at any time. To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{radiation astronomy resources}} and {{principles of radiation astronomy}} templates. 1 The average energy loss of the particle per unit path length? 2 Yes or No, Beta particles (electrons) are more penetrating than alpha particles, but still can be absorbed by a few millimeters of aluminum. 3 Radiotoxic alpha radiation emitters which are expensive? 4 The time after each event during which the system is not able to record another event? 5 Complete the text: 6 True or False, A delta ray is characterized by very fast electrons produced in quantity by alpha particles or other fast energetic charged particles knocking orbiting electrons out of atoms. 7 The auroral green line at 557.7 nm has been suggested as originating from which of the following elemental emission lines? 8 Complete the text: 9 A NASA Hubble image of the Ring Nebula contains which of the following? 10 Which of the following are associated with Type-Ia supernovae as a standard candle? 11 Which chemical phenomenon are associated with the Earth? 12 Complete the text: 13 Red-giant stars have (or theoretically may have) these in common: 14 Which of the following is not a phenomenon associated with violet astronomy? 15 Beta rays, or beta particles, are more penetrating than what other Greek letter designated rays or particles? 16 Which of the following emission/absorption phenomena are associated with radiation astronomy? The radiation astronomy of beta particles (electrons and positrons as a group) may provide insight into fusion reactions above the Sun's photosphere.
