The Radiation Protection Principles, Legal Provisions And Practical Arrangements

Introduction

Is nuclear waste is a better future? Radiation is used in many parts of the world in the field of therapy for removal of tumors and cancer, are used as weapons produced in the industry, etc. Recently, people have been discussed a lot about nuclear energy, which seems to be the best solution to solve all the worsening energy crisis. But despite all the advantages of using nuclear energy, a major disadvantage release of radiation, is still force people to support the use of nuclear energy.

Discussion

Radiation releases energy while the neutron decay of some radioactive isotopes, which are not sustainable. These energies are released in different forms, which are classified into alpha and beta particles, gamma rays and neutron radiation. 2type radiation penetrates blocks characterization of alpha-radiation skin sheet of paper harmful to the beta radiation light into the body of a sheet of aluminum foil Gamma rays pass through the body of a few cm of lead or concrete, or water meter neutron radiation pass through the body meters concrete most powerful of all.

Radiation can also be found in nature, they are called background radiation from the soil is radioactive substances such as uranium, thorium, radium, and radioactive gas radon, which is constantly running into the atmosphere, these emissions are generally considered not harmful since the concentration is too low. After the radioactive material has gone through the process of disintegration that produces most of its energy, is left of it is usually more harmful and they are called radioactive waste, or rad waste, which can be divided into 3 categories: low-level waste, intermediate, waste, and high level waste .4 type delighted sources of waste disposal methods consist of waste low-level hospitals, laboratories, industrial plants and nuclear fuel cycle, paper, rags, tools, clothing, filters, buried in shallow areas of the landfill intermediate ingressions reactor decommissioning wastes, chemicals and components of the sled reactor and contaminated materials solidified in concrete or asphalt or buried in the soil and the department depends on its time it remains a dangerous high level waste from nuclear reactors, nuclear power plants the fuel itself and the principal waste from reprocessing check and print correctly in order to keep underground.

Waste can also be classified according to their life. Half-life time required for a given radioactive isotope to lose half its radioactivity, which decreases with time, as these isotopes decay into stable, not radioactive. The decay rate of isotopes is inversely proportional to its half-life, short half-life means that it decreases rapidly. According to a level that they are dangerous and their lives, and various waste will be treated differently. For low and intermediate level waste? Concentrate and concrete? and? dilute and disperse? are the most common ways.

Although high-level radioactive waste, reactor fuel or used, it should be treated differently from? Delay and decay?. For most cases, if a high level has a long life, they will be ceramic ...
