If a nai scintillator yields 5000 scintillation photons on average for a single 140 kev gamma ray absorbed via photoelectric effect, approximately how many scintillation photons will be emitted for the imaging photopeaks of in-111 (171 kev and 245 kev)? why is the difference in the number of scintillation photons per energy important?

scientific laws are the result of testing theories and proving them to be facts.

the components of a vector are the parts of the vectors that are to each other.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
