The risks associated with ionising radiation in medical imaging Assignment

The risks associated with ionising radiation in medical imaging practice, and the precautions required to protect aginst them - Assignment Example Due to the in effective training and inadequate awareness given to the staff as well as the patients they are exposed to more unnecessary radiation (Koenig et al 2001). Ionizing radiation is used in applications such as medical imaging in the hospitals and to perform diagnostic imaging. In the medical imaging, the most common forms of the ionizing radiations are the gamma rays and the x-rays. These medical imaging practices are important in the medical field because of the determination of the diseases and different injuries in the human body. However, aside from these benefits and life saving tool, these ionizing radiations has certain limits and conditions to be applied on the patients and people. The reason for this is due to the fact that high doses of these ionizing radiations are responsible for the formation of cancers. The ionizing radiation in the medical imaging is found to be one of the most important discoveries of the medical science. Even with the use of the new technol ogy, the equipments are highly capable of posing high radiation doses if the treatment procedure is not well maintained and followed (ICRP 2000). Whereas there is a strong debate going that the usage of these ionizing radiations may cause genetic mutations and cancers. As it is well known that there is no such dose below which there is no risk of any harm to the exposed one or a zero risk (ICRP 1990). So it is important to avoid the exposure to these ionizing radiations but how can this be possible. Of course someone that needs medical attention and for different diagnosis, one has to go through these treatments, but on the first hand the primary cure is to improve the life styles and the determinants that may cause the health damage to be improved. Below is the typical effective dose from x-ray radiation. Exam Effective Dose mSv (mrem)1 Chest (LAT) 0.04 (4) Chest (AP) 0.02 (2) Skull (AP) 0.03 (3) Skull (Lat) 0.01 (1) Pelvis (AP) 0.7 (70) Thoracic Spine (AP) 0.4 (40) Lumbar Spine (A P) 0.7 (70) Exam Effective Dose mSv (mrem)2 Mammogram (four views) 0.7 (70) Dental (lateral) 0.02 (2) Dental (panoramic) 0.09 (9) DEXA (whole body) 0.0004 (0.04) Hip 0.8 (80) Hand or Foot 0.005 (0.5) Abdomen 1.2 (120) By improving our health status and also improving our physical mental and social states, we can avoid these threats even at the first place to be exposed by such ionizing radiations even for the diagnosis. However the main concern regarding the ionizing radiation is the induced cancer among the young children from the CT scans. As the young children are more susceptible to get the cancer as compared to the elders, so the more controlled experiments and discoveries are to be made in order to avoid this risk of more cancer due to these ionizing radiations. But another debate that why the need for these medical imaging are increasing day by day even with the more sophisticated technology and new era of research, does that means that science failed to improve the health st atus of the world’s population even with the advancement. The answer could be controversial as the health is comprehensive phenomena and does not depend on one facto but many. So there is a need to improve the

Team Building - Term Paper Example In this regard, there are team building exercises that have been proven to assist in conflict resolution in an organizational setting. The objective of this essay therefore, is to present and describe a team-building exercise for conflict resolution that could be applicable in an organizational atmosphere. Team-Building Exercise Usually, the sources of conflicts within groups are the incongruence of goals, interests, and lack of accurate perception of each member’s personalities and preferences. Conflict behavior could be manifested through overt (or covert) expressions of hostility between members of the group and deliberate interference with each other’s activities. Human behavior practitioners have identified a number of approaches to resolve conflicts within groups through group meetings, brainstorming, group dynamics and team-building exercises, and sensitivity training (Martires and Fule, 2004, pp.114 – 118). Group dynamics and team-building exercises are t echniques that enable group members to articulate their actual experiences, emote their feelings, sentiments and emotions on certain aspects, areas or problems with the aid of a facilitator. The process helps members get a clear understanding of the problem and gain insights into the situation. One example of team-building exercises that can be presented within an organizational setting is the Brown Bag Discussion (Destination Imagination, n.d., p. 6). The details that indicate the goals, materials, directions, and variations are as follows: Brown Bag Discussion â€Å"Goal: To have an opportunity to discuss group issues in a fair way Materials: Small pieces of paper, paper bag Directions: Have each person write down, on a small piece of paper, the topic that they think the group should discuss most. Have them fold the paper twice and deposit it in the bag. Shake the bag and take turns drawing out a topic, reading it and discussing it. Make sure that the person who wrote the topic i s satisfied with the discussion before you move on the next topic. Remind people to use "I "statements. Variations: Have the group write down questions to make it a an icebreaker, or write down different quotes and draw them out one at a time and talked about what they mean to the group† (Destination Imagination, n.d., p. 6) The exercise is simple to understand and to implement within the organizational setting and requires very minimal materials that are easy to procure. Further, as the directions indicate, the topic that the group could focus for the discussion could be the current conflict being experienced among group members. By doing so, with the assistance of a facilitator, the members would be illumined on the possible ways to resolve the conflict as heard from the insights and comments of each member. Also, to lighten up the discussion, the variation is a helpful technique that could provide an ice breaker for the discussion; rather than merely focusing on the serious ness of the conflict resolution topic. An ice breaker could be in the form of group activities that require actions, games, and even fun endeavors that would stimulate much needed respite from the formalities of the discussion. In the end, the facilitator should identify which among
