Mass Stopping Power and Range of Alpha Particles in Biological Human Body (Water and Eye Lens Tissue)

Arwa Alshibel, Khalda T. Osman
We used the MATLAB Program to calculate the mass stopping power and range of alpha particles in biological human body tissues (such as water and the eye lens tissues) at energies between 0.2 and 200 MeV. The Bethe Block formula was used to calculate the mass stopping power, and the simple integration (continuous slowing down approximation) method was used to calculate the alpha particle ranges. Empirical formulae were developed to determine mass-stopping power and ranges of water and eye lens ti...

Design and Monte Carlo Simulation of a Novel Irradiation Device

Xiaoxiao Li, Yi Gu, Baolin Song
In order to facilitate the calibration and scale of pyroelectric detectors for environmental dose monitoring, a new simple standard irradiation device was designed. Through Monte Carlo software, the uniformity of radiation field, absorbed dose of pyroelectric detector and scattering contribution rate of this device are simulated. The simulation results show that the new simple standard irradiator satisfies the national standards and can fulfill the calibration and scaling requirements of pyroele...

Nuclear Binding Energy (B) Calculation without Quantum Mechanical Correction

Barbaro Q. Leyva
A Yukawa-type potential was used to predict B for the current nuclides using a set of 23 nuclides as the source of the experimental values. The deviation between measurement and prediction was remarkably reduced by a special search on the average distance between nucleons. The best results were obtained for a 2-exponential model. The predictions of B inside and outside the range of A and Z used to do the fitting were carried out by fitting the obtained values of the average distance between nucl...

Possible Accidents Scenarios in Zaporizhzhia Nuclear Power Plant

Assef Molhem
This article discusses the implications of the Ukrainian military conflict on the safety and security of Zaporizhzhia Nuclear Power Plant (ZNPP). We have used some simplified models to calculate the boiling and boiling-off times of water in the spent fuel pools to estimate the impacts of complete shutdown of cooling systems and the probability of dangerous accidents in storage facilities. Our data confirm that this probability is not negligible, so, this factor of risk should be taken into consi...

Study on Thermal Neutron Sensitivity of Boron-Lined Ionization Chamber

Hui Li, Rui Yang
With the development of science and technology, neutron detection plays an increasingly important role in many fields, such as national defense security, medical imaging and aerospace. Gas detector is a commonly used neutron detector. It takes gas as the working medium and produces electrical signal by ionization effect of incident particles. In recent years, as the expensive price of 3He gas detector, and environmental hazard of BF3 gas detector, the boron-lined ionization chamber, which is dev...

The Review of Prompt Gamma Activation Analysis

Ling Zhang, Peng Wu, Wenchao Zhang
Prompt gamma activation analysis (PGAA) has the characteristics of high sensitivity and non-destructive analysis. At the same time, compared with neutron activation analysis, prompt gamma activation analysis requires less neutron flux and causes lower induced radioactivity to the sample. After a period of time, the radioactivity of the sample will be reduced to a natural level and can be used for other studies. Therefore, PGAA is also a suitable choice for some precious samples. PGAA has been ap...
