Abstract

Ionizing radiation is emitted from the result of radioactive materials. The scientific regular measure of dose was quantified according to the exposure of radiation to ward human being. The aim of the study was assessing the amount of dose level and its consequence that effect toward human being. The importance of this work was judged based on how much was questioned and the path ahead for people to defend themselves from radiation exposure. The present work was conducted by using gamma spectroscopy to determine the radiation dose level of ionizing radiation. It was checked of quantification dose which incorporates the total amount of ionizing radiation that is associated with damage the tissue. It was determined that absorbed and Annual equivalent dose of natural occurrence of radioactive material. All human being are exposed to ionizing radiation with natural cosmic rays coming from outer space and image therapy within in hospital. When it seen that the exposures were varied as of people immunity. The sources of radiation exposures to the human were estimated based on the dose which affects the organ. Radiation exposed was leads serious gene and cancer disease. Generally, in this survey we assessed that particularly ionizing radiation caused damaged short and long term effect.

Highlights

Ionizing radiation occurs at the highest frequencies
We discussed the effect of radiation dose on the natural occurrence of radioactive materials
We discovered that the radiation dose was proportional to the projectile particle of energy

Summary

Introduction

Ionizing radiation occurs at the highest frequencies. The process of transforming a neutral atom or molecule into an electrically charged component is known as ionization. The natural sources of ionizing gamma radiation in the environment can be classified into terrestrial and Cosmo genic radiation sources. Terrestrial radioactivity comes from the ground and Cosmo genic radioactivity comes from the interaction of atmospheric gases with cosmic rays. Among these natural ionizing radiation sources, cosmic radiation contributes only to the external exposure of humans, whereas cosmic radiation induced radionuclides (for example 14C) and terrestrial radionuclide’s contributed to both external and internal exposures [2]. The level of radioactivity varies depending on the composition of rocks. Radioactive materials are produced in volcanic rocks like granite and pumice. Radioactivity, absorbed dose, exposure and dose equivalent too are measured in different units. The dose equivalent is the same as the absorbed dose for beta and gamma radiation but larger than the absorbed dose for the more hazardous alpha and neutron radiation [4]
