Poisson Distribution of Radioactive Decay
نویسنده
چکیده
In this experiment we observe the distribution of radiation emitted by a Cs source. Using a scintillation counter, we count the number of gamma rays emitted by the radiation source at four different mean count rates: 1 sec−1, 4 sec−1, 10 sec−1, and 100 sec−1. From this we can plot the distribution of counts/sec versus the frequency of count rate. We find the distributions for the different mean count rates comparable to Poisson and Gaussian distributions. We also find that the Gaussian distribution can approximate the Poisson distribution very well at high mean rates.

Poisson Statistics
Prior scientific knowledge has shown that the radioactive decay of nuclei can be modeled as a series of independent, random events. [1] The probability for the occurence of such events can thus be modeled by Poisson statistics. In this experiment, we studied the radioactive decay of Cs by using a NaI scintillator. We recorded the counts per second for 100 consecutive one-second long intervals a...
متن کاملDoes the radioactive decay obey the Poisson statistics ?
It is shown that a nontrivial quantum structure of our space at macroscopic scales, which may exist as a relic of quantum gravity processes in the early universe, gives rise to a new fundamental phenomenon: spontaneous origin of an interference picture in every physical process. This explains why statistical distributions in radioactivity measurements may be different from the Poisson distribut...
متن کاملPoisson Statistics of Radioactive Decay
Poisson statistics were studied using the radioactive decay of Cs as a source. A scintillation counter measured gamma rays emitted by Cs as well as background from cosmic rays and other experiments in the laboratory. Data from approximate mean rates of 1, 4, 10 and 100 counts/sec was compared to both theoretical Poisson distributions and Monte Carlo simulations. The reduced chi squared values f...
متن کاملMeasured PET Data Characterization with the Negative Binomial Distribution Model
Accurate statistical model of PET measurements is a prerequisite for a correct image reconstruction when using statistical image reconstruction algorithms, or when pre-filtering operations must be performed. Although radioactive decay follows a Poisson distribution, deviation from Poisson statistics occurs on projection data prior to reconstruction due to physical effects, measurement errors, c...

Introduction: Nowadays, cancer is one of the most important concerns in human being's societies, more than one-third of people in around the world will get cancer during their lives. Physical dose depth distribution characteristic of protons in a tissue is determined with a low dose in the entrance region, maximum dose in the Bragg region, and rapid decline takes place near the...
