particleShield
particleShield is a Python library designed to facilitate radiation shielding calculations. It provides a set of functions and utilities to determine the amount of radiation absorbed by different shielding materials for different types of radiation.
Features
This Python code provides a set of functions to perform various calculations related to radiation physics, including:
Half-value layer (HVL) calculation
Buildup factor calculation
Dose rate calculation
Radiation attenuation calculation
Bethe-Bloch equation for energy loss
Bragg curve generation
Requirements
Python 3.7
NumPy
Matplotlib
Installation
Make sure you have Python 3.7 installed on your system.
Install the required dependencies by running the following command:
pip numpy as np, matplotlib.pyplot as plt
Download the particleShield library and import it in your project.
Usage
The package can then be imported using:
import particleShield
Ionizing Radiation
particleShield provides multiple functions for calculation of radiation protection and dosimetry for different types of ionizing radiation.
#Calculate the half-value layer
hvl = particleShield.calculate_hvl(initial_intensity, attenuation_factor)
#Calculate the buildup factor
buildup_factor = particleShield.calculate_buildup_factor(penetration_depth, attenuation_factor)
#Calculate the dose rate
dose_rate = particleShield.calculate_dose_rate(intensity, conversion_factor, time, distance)
#Calculate radiation attenuation
attenuated_intensity = particleShield.calculate_attenuation(I0, mu, x)
Beth-Bloch equation
The Bethe-Bloch equation is used to calculate the energy loss of charged particles (e.g., electrons, protons, alpha particles) as they pass through a material. It describes how these particles lose energy through ionization and excitation of atoms in the material.
#Calculate energy loss using the Bethe-Bloch equation for Protons in Air
kinetic_energy = 100 # MeV
charge = 1 # Elementary charge units
atomic_mass = 28.09 # g/mol
atomic_number = 14
ionization_potential = 78 # eV
energy_loss = bethe_bloch(kinetic_energy, charge, atomic_mass, atomic_number, ionization_potential)
print("Energy Loss:", energy_loss, "MeV/cm")
Output: Energy Loss: -4.297 MeV/cm
Bragg Curve
The Bragg curve is a graphical representation that illustrates how the energy deposition of charged particles varies with depth as they traverse a material.
#Generate the Bragg curve for protons in air
alpha = 0.1666 # MeV/(g/cm^2)
p = 1.76 # g/cm^2
shallowest_depth = 10.0 # cm
deepest_depth = 15.0 # cm
generate_bragg_curve(alpha, p, shallowest_depth, deepest_depth)
