ABSTRACT
This research work tends to assess “Comparative Analysis of Radiation Protection Measures in Government Owned Hospital and private Diagnostic Centers in Enugu”. The objectives of this research study includes: to investigate the effectiveness of radiation shielding by both government hospitals and private diagnostic centers while using it in medical practice.
To examine the extent of exposure of radiation by government hospitals and private diagnostic centers. The researcher made use of both primary and secondary sources of data collection in sourcing information necessary for the research study.
The data collected was analyzed with the aid of simple tables and percentage, while the hypotheses were tested with chi square. The summary of findings made for the purpose of this research work includes the following: radiation shielding by both government hospitals and private diagnostic centers is effective.
There are differences and similarities between the radiation protection measures adopted by government hospitals and private diagnostic centers.
The researcher therefore recommends that: both government hospitals and private diagnostic centers should adopt modern and effective radiation equipments to further enhance their radiation shielding. These hospitals should adopt effective protective radiation measures to prevent complications in their radiation practices.
In conclusion, both government hospitals and private diagnostic centers have been able to practice effective radiation protection administration with their patients and staff.

INTRODUCTION
1.1 BACKGROUND OF THE STUDY
According to Thomas, Edison and William J., the word «radiation» (translated from Latin as «radiance») is used to signify an energy, which radiates and spreads as waves and particles1. While there are numerous types of radiation (visible light, ultraviolet radiation, heat (infra-red) rays and radio-waves), the word «radiation» is most often used to signify «ionizing» radiation.
Radiation is defined as «ionizing» due to its capability to cause atom/ molecule ionization (their splitting into negatively and positively charged particles) in a substance.
Electromagnetic ionizing radiation according to ICRP, comprises roentgen rays as well as gamma rays emitted by radioactive elements2. By nature, radio-waves, visible light and ultraviolet rays are also electromagnetic radiation, though their energy is insufficient for ionization. The rest of ionizing radiation is represented by particles. For instance, beta particles are electrons, alpha particles are helium nucleuses and neutrons are uncharged particles.
Penetrability is one of the most important characteristics of various kinds of radiation. The higher the density of the particles’ energy transfer, the quicker the particles lose energy and cease to move. Such particles, for example, alpha rays, cannot penetrate deep into the material. Therefore, a sheet of paper is enough to protect oneself from them. Gamma and roentgen rays are the most penetrative, thus explaining the large number of protective shielding in an X-ray room.
The term «dose» is used to quantify a radiation impact. In assessing the health effects of radiation, a radiation dose is the most important characteristic.
The term «exposure dose» is used for radiation characteristics. Ionizing radiation causes an ionization effect in the air. The exposure dose shows how many ions occur in a certain airborne volume. For many years, a miscellaneous unit, roentgen (R), indicating a number of ions formed in 1 sm3 of the air, has been used for these purposes. Though the unit is presently outside the list of dosimeter indices, in practice it is still widely used.
All types of radiation impact living organisms by transferring their energy to them. The absorbed dose is an ionizing radiation energy transferred to a substance (for instance, the human body). While the absorbed dose is measured in Grays (Gy), a miscellaneous unit rad (1 Gy = 100 rad) is sometimes used. These units show an amount of energy absorbed in a unit of the substance mass.
Various kinds of radiation affect living organisms differently. At one and the same absorbed doses, neutron radiation would have effects 10 times and alpha radiation – 20 times more severe than roentgen radiation. The term «equivalent dose»takes into account the factor. The equivalent dose unit is Sievert (Sv), the former unit being Rem (1 Sv = 100 Rem).
Both scientific and technological progress has created an environment in which both natural and manmade emergencies may occur. Since it is impossible to exclude the potential for radiation accidents completely, awareness of emergency procedures, realistic prediction of probable consequences, and adequate protective measures are critical to preventing or at least mitigating possible damage.
Radiation protection at workplaces starts with structures, components and systems which are designed to optimize the staff safety, includes an adequate use of radiation protection aids, and is rounded off by appropriate organizational measures.
In government hospitals in Enugu state film badges, thermoluminiscent dosimeters and pocket ionization dosimeters are the recommended radiation measuring devices for use by radiation workers to monitor received radiation dose.
Every worker is expected to wear his/her personal dosimeter always while working. The dosimeter readings are kept as records for every staff for the purpose of evaluating their radiation history and possible risks involved. The records help in improving radiation protection practices in clinical settings.
STATEMENT OF THE PROBLEM
This research study addresses the following problems:
The ineffective shielding of radiation by both government hospitals and private diagnostic centers while using it in medical practice have caused a whole lot of problems.
This is due to the fact that the effectiveness in shielding of radiation is dependent on the Stopping power of radiation particles, which varies with the type and energy of radiation and the shielding material used.
Allowing for prolonged exposure by both government and private diagnostic centres has led to a diversity of complications. This is often deleterious to body cells of the people exposed to irradiation. Ineffectiveness in the use of radiation instruments by both government and private diagnostic centres has drastically affected the essence of these instruments.
This is due to the fact that these instruments are used in evaluating the effectiveness of protection measures, and in assessing the radiation dose likely to be received by individuals. This also leads to ineffective protection measures in these health centers.
OBJECTIVES OF THE STUDY
The broad objective of this research study is to comparatively analyse radiation protection measures in government hospitals and private diagnostic centres in Enugu.
