What is the basic principle of scintillation detectors?
What is the basic principle of scintillation detectors? a. The basic principle of pulse height spectroscopy is that the light output of a scintillator is proportional to the energy deposited in the scintillation material. The standard way to detect scintillation light is to couple a scintillator to a photomultiplier. What is scintillation efficiency? Scintillation efficiency […]
Why atoms tend to lose and gain electrons?
Why atoms tend to lose and gain electrons? Most atoms do not have eight electrons in their valence electron shell. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are […]
What is carbon 14 used to date?
What is carbon 14 used to date? Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. What is the lifespan of carbon 14? Carbon-14 has a half-life of 5,730 […]
