Essays on Radiation Protection

Introduction

Reliable and sound information is the key source of decision-making across all healthcare centers worldwide. Effective information systems are essential for the development of health system policies and their implementation. In addition, it ensures good governance and regulation, promotes health research, improve human resources development and high service delivery. Advances in technology, especially the internet, creates a better opportunity to improve healthcare institutions through making communications more efficient and increasing the effectiveness of practitioners. Healthcare centers that have implemented information systems have realized great changes in their operations in terms of speed, safety, efficient communications between parties and cost cutting. ...

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). ...

Introduction

It is generally noted that the development of dosimeters to measure neutron exposures has been slow for many years in comparison to the development of gamma and x-ray dosimeters. Exposures to x-rays and gamma rays have been determined from glass dosimeters and film badges. By applying these dosimeters, personnel exposure to radiations caused by radioactive substances can be measured to standard accuracy. However, the uncertainty may arise due to variation in readings as a result of orientation of the wearer of the dosimeter to the source during exposure. On the other hand, NTA film has been the only neutron dosimeter ...

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

Every year, very many workers all over the world are injured, adversely affected or even die from the radiations emitted from the production processes in various industries. This has raised concern for the industrial hygienists, since radiations have posed a threat to the workforce and the community in general. Ionizing radiation has the most damaging effects to human health. Therefore, protection against such fatal radiation is necessary: the workforce should be protected as well as the community. Generally, radiation is the means through which energy travels from one point to another. Other definitions define radiation as an energy that ...

Most equipment used in healthcare centers produce harmful radiations affecting many medical staffs. A quality designed textile could assist in blocking these radiations from entering our body and causing harms (Akopian et al 1999). The current lead aprons available in the market have shown many problems. In some instances, workers complain of back pains due to the weight of these garments. In addition, the lead aprons used today have low level protection exposing workers to most radiations and have proven insufficient in providing the necessary protection exposing healthcare staff to radiation risks (United States Department for Labor 2003; Allianz ...

Healthcare workers are exposed to a lot of radiations coming from the sun and artificial sources. These radiations cause many health problems to the affected individuals and their generations. The magnitude of the skin to resist some radiations depends on the climatological factors and personal sensitivity to Ultra Violet Rays (UVR). Ultraviolet Rays are the most dangerous in the electromagnetic spectrum and the wavelength bands. This project describes the tests and methods necessary for establishing a radiation protection program on the skin using fabrics. The utilization of intelligent medical textiles in the healthcare centers has a enormous potential of changing the healthcare ...

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 ...

Introduction

Unstable nuclei give rise to radioactive isotopes. Although there is a general belief that these isotopes are because of human activities quite a number occur naturally. Most of the radiations that we receive on earth have natural sources. The cosmic rays originate from space and other radioactive isotopes and we expose ourselves to daily. The most significant aspects of these radiations are their ability to transmit energy in terms of waves. The various forms of radiations include the visible light, radio waves and microwaves, which do not have to carry with them enough energy to ionize. Ionizing radiations are the ones, ...
