Poisson Statistics of Radioactive Decay

چکیده
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 for the fits to theoretical distributions ranged from 0.57 to 2.13. The values from the Monte Carlo simulations were within the margin of statistical error of the data. Thus, it was found that gamma rays from the radioactive decay of Cs with added background events is accurately modeled by Poisson statistics, so each decay event in a bulk source is a random, independent event.

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 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: Internal exposure to radon gas progeny can lead to serious biologic damages to the lung tissue. The aim of this study was to evaluate the absorbed dose by lung tissue due to the exposure from short-lived radioactive products of radon (222Rn) decay using Monte Carlo simulation. Material and Methods: A lung equivalent p...
متن کاملPoisson Distribution of Radioactive Decay
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...
