Abstract

The uses of radiation revolutionized medicine when experimentation on its potential applications begun. X-Ray technology, discovered by Wilhem Roentgen, is currently used as a common tool for diagnostics; Henri Becquerel, Marie Curie and Pierre Curie dedicated themselves to further investigations in the field, discovering additional radioactive materials (polonium and radium); radiation therapy is a popular treatment for cancer. This paper analyzes the historical background behind these two applications of radiation in the medical field. Moreover, the different types of radiotherapy are described (external-beam radiation therapy, internal radiation therapy). The concept of radiation homeostasis, which is the notion that low-dose ...

Nuclear Weapons

Development of the nuclear weapon was a phenomenal step for science, but one of the worst inventions in human history. As a weapon that is so deadly it can wipe out entire large populated cities at once, the world lives in concern of all the nations of the world who have nuclear weapons in their possession. It was the United States that developed this bomb and first used them in World War II by dropping them on Hiroshima and Nagasaki in 1945. After the use of these weapons by the U.S. other nations began testing them as well, such ...

The progress made in the field of aviation has reached new paradigms. The simple airframe of the Wright Brothers has been modernized beyond belief. Although this industry has been claimed as the frontier of men, none can overlook the significant contributions made by women aviators. Women have been able to break the glass ceiling and rise to the highest levels in the aviation industry since 1903. Despite the laws and policies that protect the rights of women, inequality between men and women still remains widespread and deep rooted especially in this field dominated by the male counterparts. Little do ...

Question 1

PCBs Polychlorinated Biphenyls (PCBs) are chlorinated hydrocarbons with two phenyl rings. They are stable, resistant to fire and possess good insulating properties. Hence, they were used widely before their ban in 1979, in transformers, capacitors, hydraulic machine lubricants, and oil based paints, adhesives, sealants, insulating and caulking material as well as in light ballasts. (US Environmental Protection Agency [USEPA], 2013). EH&S as well as FS personnel would have to handle PCBs when they indulge in building demolition, renovation, decontamination activities or in case of emergencies such as fire and explosion. PCBs present in electrical and building materials pose a ...

The aim of the research is to provide a solution to the problems that arise due to the high doses of radiation. Radiation is used in the treatment of diseases that involves the usage of high radiation therapies such as X-rays, CT scans, ultrasound scan and MRI scan. Major radio therapy techniques have led to adverse effects on patients due to the excess dosage of radiation. The research would help to reduce the harmful effects caused by the exposure to radiation by designing radiation protection programs that protect workers, patients and the environment. The newer X ray and CT scan ...

- DETAILED DESCRIPTION OF PROPOSED PROJECT - Aims and objectives The health risk assessment of MRI is incomplete yet and a number of gaps in our knowledge about the ill-effects of MRI have been identified. The effects of exposure to static fields above 8 T are not known. Only a little is known about the increased sensitivity of some people to CNS stimulation by the electric fields in switched gradient fields. There are concerns about the increased heat loads on infants and pregnant women. Hence, well-targeted research is required to complete the health risk assessment (Health Protection Agency, 2008). ...

Nuclear medicine is a technique used in diagnosing and treating diseases using small amounts of radioactive materials. The technique utilizes the radioactive decay process and relies on radionuclides which are described as radioactive isotopes that can be traced by a gamma camera connected to a computerized system. The amounts of radionuclides introduced into the body is carefully selected to ensure that it only offers the accurate diagnosis and treatment results without exposing the patient to levels of radioactive material that would be harmful to them (Nuclear Medicine). These radionuclides are introduced in the body through several methods. It can be done through ...

Radiologists and the complementary professionals and para-professionals face unique risks while at the work place. Exposure to ionizing radiation induces nuclear changes in cells that may cumulatively lead to cancer. In the case of the patient, the exposure to radiation is necessary in order to establish diagnosis or treatment and the benefits should outweigh the potential harm. For the staff on the other hand exposure to increased levels of exposure is hazardous and undesirable. Shielding is used to avoid accidental exposure to radiation, as well as careful obedience to the laws of physics. The effects of radiation lessen as ...

Introduction

On the quiet morning of August 6, 1945, the United States shocked the world by dropping an atomic bomb over the city of Hiroshima, Japan. Hiroshima was a main industrial city with that had a projected population that was somewhere around 400,000 individuals. On a bright day, A B-29 bomber was loaded with the Atomic Bomb and shipped out of the air base at 2:45 a.m. local time and the next thing people knew, an entire city went up in smoke at exactly 8:15 a.m. This essay will examine the atomic bomb and the devastating effect it had on the Japanese ...

Light and heat are the common types of radiation that human beings know. This is because the two can be seen and felt. However, there are other kinds of radiation that cannot be detected by human beings. In many cases, human beings constantly receive this invisible radiation either from the ground, air or sky. They can as well be found in processed drinks and foods. Ionizing radiation can be used in many fields; including hospitals where doctors use X rays in the diagnoses of injuries and other disease; industrial unit where they are used in checking repairs in components ...

As exploitation of nuclear energy continues, safety and security should be given prime concern .All forms of energy have draw backs with positive impacts of one form being recommended mitigation steps to negative impacts of another form of energy and vice versa. Nuclear power exploitation has been rewarding in offering full time employment opportunities at every facility at the same time being a source of revenue to governments, guaranteeing non –interrupted supply of electricity enhancing energy security as they have larger generators of electricity efficiently full filling base load demands.

Introduction

Radiation is best described as energy which is passing through space or a medium (Khan 2010). There are two categories of radiation; non-ionizing and ionizing radiation. Non-ionizing radiation is important in the life systems and can be exemplified by heat, visible light, or radio waves; however, overexposure may be toxic. Ionizing radiation is the one commonly implied whenever the term radiation is used. Ionizing radiation has enough energy to change atoms which may result in changes in cell molecules leading to alterations within the cells and thus cell damage. Radiation is measured by the unit, rem, which is ‘roentgen equivalent ...
