The Effects Of Radiation And Its Effects On The Human Body

Over the past few decades one of the main arguments patients have when going to see a dentist is the amount of radiation they are exposed to while taking dental radiographs. Every time this happens the dentist has to sit the patient down and talk to them about the cause versus effect. While many patients think that they are being over exposed to radiation while having a standard set of x-rays every year, they never take into account the amount of radiation that they are receiving through other devices of by just walking outside. Not many dental providers think of the amount of radiation they are receiving just by working with it every single day. The lack of knowledge that dental providers have about radiation exposure can affect their overall

Cancer is a genetic, heritable disease in which abnormal cells divide rapidly destroying normal body cells, often being fatal. Cancer can occur in any body tissue; skin, organs, and parts of the reproductive system (Duda). There are various activities linked to different types of cancer, such as smoking, too much sun exposure, gene mutations, carcinogens, and viruses. A major cause of cancer, dating all the way back to the 1950’s, is radiation. Atomic testing ordered by the U.S. Government has been suspected to be the cause of many deaths linked to radiation-related diseases (Williams 149).

There are two reactions that happen in the human body when ionizing radiation within the diagnostic range (30-150 kilovolt peak) is

According to Ecker and Bramesco, the majority of the understanding of the effects of radiation comes from the research from the atomic bombings of the town of Hiroshima and Nagasaki (107). There is a greater effect when a dose of radiation is given all at once rather than over an extended period of time (105), However, as soon as radiation hits an individual there are some immediate effects and more long term effects. Some long issues that has come up due to the radiation of the atomic bomb were the more frequent cases of leukemia, cancer, and cataracts than people who weren’t affected from radiation (Ecker and Bramseco 107). Also, mutations can be a long term effect. Naturally, mutations occur at a low rate. Radiation can increase the number of mutation cases because it is a mutagen (Nasr and Hoyle). Some short term effects would be radiation sickness called acute somatic effects. Acute means severe and somatic means ‘related to the body’. The first signs of radiation sickness are nausea, throwing-up, and fever and

This is a unit of measure of ionization in air, the quantity of radiation that produces one electrostatic charge in 1 cm3 of air. Radiation dose is the amount of energy absorbed by a tissue at a specific point. The rad is a unit of absorbed dose (the amount of energy absorbed by tissue) and is defined as 100 ergs of energy per gram of tissue (or rem). A localized dose of radiation is a rad of radiation to the localized area. Every gram of body tissue in that area absorbs one rad. When concerning total body dose in dentistry, the x-ray machine delivers a localized exposure with a single radiograph that results in a total body exposure approximately 1/10,000 of the facial exposure. X-rays have no effect on the nucleus of the absorbing atom, affecting only the atom’s orbiting electrons. Although the equipment and walls are receiving radiation in a dental operatory, they do not become

Due to some circumstances being out of our control, whether it is through natural means of toxicity from radiation or unnatural means of radiation, how do we protect ourselves? The Earth is covered in natural background radiation. Terrestrial, cosmic and radon radiation are all a part of our environment. Even if manmade radiation and nuclear radiation didn’t exist, we would still be exposed to toxic, unhealthy sources of biological changing substances. How do our bodies recover from an assault to our immune systems and resume a healthy life from ionizing radiation that can cause cancer? How do we become proactive, and responsible for our own health outcome? Can we eliminate from our bodies unwanted toxins, carcinogens, free radicals, and ionizing substances? Do we have control over our health after a large dose of radiation from a nuclear accident, or treatment from radiation therapy? Evidence shows that we do. Just as there are natural sources of radiation, there are natural ways to cleanse our bodies and use nutrition to detoxify, rejuvenate, and restore health when our immunity has been compromised from natural or unnatural sources of radiation.

I interviewed Martha Dibb over the phone to see what her life is like working at Gundersen as a radiation therapist. Martha is a relatively new radiation therapist that graduated from La Crosse two years ago. Her bachelors in radiation therapy is the only degree she has up to this point. She does not plan to pursue any managerial roles at this point in her career, but she does have an open mind. She completed her internship at Gundersen and said she really loved doing her internship there. After she graduated she received a job at Aurora in Kenosha, and she worked there for nine to ten months before getting a job as a radiation therapist back at Gundersen. She has now worked at Gundersen for about eight months and really seems to enjoy working there. I asked her if there were any difference between Gundersen and Aurora and she said there actually is a lot of difference since Aurora in Kenosha was a small radiation center. According to her when she worked in Kenosha the radiation

Ionizing radiationHelpIonizing radiationRadiation with so much energy it can knock electrons out of atoms. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. has sufficient energy to cause chemical changes in cells and damage them. Some cells may die or become abnormal, either temporarily or permanently. By damaging the genetic material

While healthy babies are born every day, not everyone is so fortunate. In many cases, diagnostic radiology is required for patients during their childhood. Can having this radiation during the formative years lead to adverse effects later in life? The biggest concern from radiation is the risk of cancer. Cancer can occur at any dose from ionizing radiation because it is a stochastic effect, meaning that it is probabilistic. The probability of a stochastic effect, such as cancer, increases as the dose increases. While receiving this radiation may be necessary, it can cause some serious trouble later in life, such as breast cancer, leukemia, and thyroid cancer.

From the website, NASA states, "The Ionization of water and other cell components can damage DNA molecules near the path the

The effects of radiation can be hazardous to any part of the human body. In this guide I will explain the advantages, and disadvantages of x-ray radiation. I will also discuss the technological advances that we have today then of what we had the past on the human body during radiation exposure. I will explain preventions of exposure and safety precautions that we as dental assistants as well as patients can follow to stay safe.

Radiation executives would eventually leverage their political savvy and astute management skills to commandeer the recently combined organization. Less than a decade after the merger, the Ohio-based headquarters of Harris relocated to Florida and elected the former president of Radiation as chief executive officer and chairman of Harris. Several years later, the last remnants of the original acquiring company sold off entirely and subsequently formed into another company known as Harris Graphics. However, the Harris name would endure as an ironic legacy. Still later, another former vice president of Radiation would succeed in those footsteps.

For this week’s discussion board, I chose to focus on selection number two, ionizing radiation effects on cells and tissues. “Ionizing radiation is radiation that produces immediate chemical effects on human tissue” (Perez 2013). Ionizing radiation exposure can be the result of industrial accidents, medical treatment, and radiological warfare. Alpha radiation (emitted from substances such as polonium-210) kills cells, “having the most effect on those that regenerate the most rapidly” (Huddersfield Examiner 2008). According to the CDC’s physician factsheet, the primary cause of Acute Radiation Syndrome (ARS) is the depletion of immature stem cells in tissues, which is caused by a minimum radiation exposure of thirty to seventy rads (2005, 1). It should be noted, however, that ARS is typically the result of medical treatment, industrial accidents, and nuclear exposure; ARS is not equivalent to radiation sickness, which can be caused in numerous ways to include ingestion.

Exposure to ionizing radiation induces oxidative damage that leads to alteration of tissue physiological function as observed in the present study. This was evidenced by significant elevation in kidney MDA content. These results match the increase in lipid peroxidation post irradiation obtained by Srinivasan et al. (2007) and Pratheeshkumar and kuttan (2011). Free radicals generated by irradiation react with unsaturated lipids generating hydroperoxides, which in turn can induce changes in lipid bilayer thereby altering the membrane permeability and inducing lipid peroxidation (Suzuki et al. 1997). Also, significant elevation of kidney GSH contents were observed in irradiated rats. This increase in GSH level may be due to transcriptional

The topic of my research paper is radiation caused illness and I chose this topic because of the radiation leak in Fukushima, Japan due to the massive earthquake and tsunami. Nearly 20,000 people were killed by the devastating earthquake and tsunami. Although there were no deaths connected with the radiation leak, there is much concern over its long-term effects. I was eager to find out how the radiation leak would affect the citizens in that area over a period of time. Radiation injury is interesting to me because I am half Japanese and have relatives living in these areas. The fear of what will happen to my relatives and the people who have been exposed to radiation greatly sparked my interest and curiosity in this topic.
