Radiation has always been in everyday life even before Roentgen discovered x-ray. The mountains give off natural radiation, other forms of radiation are coal burning power plants, x-rays from a TV, and an airplane ride. The average dose from background radiation is about 360 mrem every year. There are two types of radiation, nonionizing and ionizing radiation. Examples of nonionizing radiation are microwaves and radio waves broadcasting. Ionizing radiation refers to gamma and x-rays. Ionizing radiation means that the rays are able to remove an electron from the atom then ions can be formed. The ions can cause damage when reacting with other atoms. Cells are able to be repaired if low dose are received. However, if cells get a high dose, the cells will be damaged or possibly die. If the cell is damaged permanently then it is referred to as a mutated cell. There are ways to better understand how radiation affects the body when compared to other every day activities. If an occupational worker receives 1 rem per year then is it possible that 51 days is expected to be lost. A person that smokes 20 cigarettes a day takes about 6 years off of their life. People that are overweight by 15% take about 2 years off of their life. In actuality radiation would seem as though it is not any more harmful than other everyday activities people decide to do such as smoke, chew tobacco, or sky dive. The risk of taking days, weeks, years off of ones lives will always be present depending on the activity they choose to be part of. However, radiation exposure in the healthcare field is used to extend the patient’s life by helping them find out what is going on in their body. A patient that comes in with RLQ pain, nausea, and vomiting then an abdomen x-r... ... middle of paper ... ...om the radiation, the source of radiation comes from beneath the patient. Spot fluoroscopy should be utilized to minimize radiation to the patient, radiologist, and radiologic technologist. Radiologist and radiologic technologist must wear a lead apron and thyroid shield. A lead shield is put on the front to protect the radiologist and the tech. (Statkiewicz-Sherer, 1983) Radiation has changed drastically over the past 118 years. Exposures are much quicker, digital imaging is a possibility in most hospitals, and most importantly, radiation protection. Many people have died, some without realizing that they were killing themselves, for the advancement of x-rays. Because of these advancements physicians are able to tell patients what is going on very quickly and without much delay. It is very important to remember the 3 cardinal rules: distance, time and shielding.
the effective doses from diagnostic CT procedures are typically estimated to be in the range of 1 to 10 mSv. This range is not much less than the lowest doses of 5 to 20 mSv estimated to have been received by some of the Japanese survivors of the atomic bombs. These survivors, who are estimated to have experienced doses slightly larger than those encountered in CT, have demonstrated a small but increased radiation-related excess relative risk for
The conversation around the rising costs of health care continues to be a high priority topic of discussion from consumer all the way up to the government. There are many products and services that contribute to the rising costs, as well as some responsibility left to practicing providers who choose to use high dollar radiology services for patient care. Ionizing radiation has been used for more than a century, however, this evolution or radiology services into widespread diagnostic and therapeutic uses has resulted in a significant increase in the population’s overall exposure to radiation with the potential to increase the risk of cancer (Amis & Butler, 2010). Examples of high dollar radiology services are services like Magnetic Resonance Imaging (MRI), Computer Tomography (CT) scans, and Echocardiograms. These services allow physicians t...
For decades, the effects of radiation has been studied by doctors around the world. X-rays are used in the medical and dental field to take radiographs of certain parts of a person's body. Some have become concerned of the long term and short term effects of having x-rays taken because of the radiation that is exposed. Since the rise of concern, studies have been done to find any type of link between cancer and radiation from x-rays. Specifically, in dental x-rays, researchers have been performing studies trying to prove that radiation from x-rays in the dental office can cause cancer .
Radiation has both beneficial and harmful effects. The most detrimental health effect on humans, is the incidence of cancer, which has been studied. Humans are exposed to radiation more than they realize. They are exposed medically with x-rays, just by being outside with cosmic rays, and by accidents such as at the Chernobyl Nuclear Power Plant. Exposure to radiation is high and more studies are done which improve radiation protection.
What Nuclear power has the ability to do is get a lot of power in a little amount of space. “Roughly 1.6 billion people live without access to electricity, and 2.4 billion rely on traditional biomass because they have no access to modern fuel.” (General Dr. Mohamed ElBaradei) With nuclear power put into these countries that are without power we can have it to where electricity will be accessibility to everyone. By having power accessible to everyone we can accomplish so much more and unlock more possibilities in our world today.
Radiation is the emission of electromagnetic energy that is given off in the form of high speed particles that cause ionization. During ionization radiation hits and knocks electrons from an atom creating charged ions. Due to the electron being stripped away from the atom this break the chemical bond. Living tissue within the human body is damaged and attempts to repair it but sometimes the damage is beyond repair.
...why does the technologist step behind a shield to prevent exposure to themself?" The radiation dose for each exam is relatively small, but over time, the dose can add up. There are many state and federal regulations limiting the total radiation dose that may be received by people working with radiation. To comply with those regulations, the technologist must follow strict precautions to keep their cumulative exposure to a minimum.
Radiation occurs when radioactive elements break apart. Radiation is very dangerous because it damages living things. There are three types of radiation, these are alpha particles, beta particles, and gamma rays. They are the first three letters of the Greek alphabet: alpha (a), beta (β), and gamma (ϒ). These particles and rays are produced by radioactive elements. Alpha particles are made of 2 protons and two neutrons that have separated from the nucleus, they are positively charged. Beta particles are usually made of one electron and a neutron, and have a negative charge. Gamma rays are a different sort of radiation. They are made of a stream of tiny particles called photons. Photons include the same particles that make up rays of light and are packets of energy. Gamma rays are very dangerous because they carry a lot more energy than the light people can see but are still invisible. Also released by radioactive elements are X-rays, they are similar to gamma rays but contain less energy.
So why is radiation so bad for us? Well, radiation is bad for you because it can cause effects on your health, more specifically your cells. Ionizing radiation can cause changes in your cells, which can possibly lead to damaging them, and in some cases, a large exposure of radiation can lead to death or illness but is usually pretty rare (EPA). William F. Morgan and Marianne B. Sowa, who are radiation researchers at the University of Maryland, conducted a study about ionizing radiation in nonirradiated cells. Nonirradiated cells are cells which have not been touched by or experienced radiation before. Morgan and Sowa published a journal article in which they talk about their research, and they stated that nonirradiated cells that are hit
How does radiation affect the health of people? Radiation caused thyroid cancer in many. Thyroid cancer use to be rare in children. There more and more findings on radiation and cancers. Radiation was instant, causing some to get illnesses. People were greatly affected then and now by the Chernobyl accident.
Also you will lose your hair very quickly if exposed to a high amount of radiation. Like the heart radiation kills cells and small blood vessels, and can cause seizures and immediate death. When a person is exposed to around 100 rems the blood's lymphocyte cell count will be reduced, leaving the victim more prone to infection. This is called mild radiation sickness. Early symptoms of radiation sickness can be a lot like those of flu and may go unnoticed unless a blood count is done. According to Hiroshima and Nagasaki, studies show that symptoms may last for up to 10 years and may also have an increased long-term risk for leukemia and
... that could cause brain loss or deformity in people. Also if the cell has too much radiation and it becomes cancerous then that could spread all across the body therefore killing the person. Doctors use radioactivity in chemotherapy to kill the bad cells in a particular part of a persons body. They have a way to aim the radiation where they want it to go then they shoot it to kill the cancer cells before they spread throughout the body. This causes the person to lose hair because there hair cells are being killed by the radiation as well.
Radiation is one of the most dangerous and easiest way of having health effects. Radiation was first discovered by Roentgen. Hazards are the first things people need to know in order to understand what it can do to your body. It causes many health effects on everyone out in the world. It harms people in the dentistry and field and even in the medical field. Normal people out the world can also be exposed when coming into one of these offices and getting x-rays of some type.
Biological effects of radiation are typically divided into two categories. The first category consists of exposure to “high doses of radiation over brief intervals of time” producing acute effects (Hall p. 15). The second category represents exposure to “low doses of radiation over extended periods of time” producing chronic or long term effects (Hall p.15). High doses tend to kill cells, while low doses tend to damage or change them. High doses can kill so many cells that tissues and organs are damaged.
Radiation in simple terms is a way in which energy moves from one place to another, which makes everything virtually radioactive, including ever human being. About one - half of a person’s radiation occurs naturally, whilst the remaining is man-made. (Miksanek, 2013) The major effects of radiation are a variable that is based on the amount of exposure that a human being has. The most notorious effect of radiation is death within a few days or weeks. An extensive number of people have died from being exposed to a significant amount of radiation. Another major negative impact of radiation exposure is cancer. Many studies have shown that a common side effect of overly exposure to radiation over time, have increased the number of cancer cases within the number of affected persons. Cancer cases such as Leukaemia (a type of blood cancer that starts in the bone marrow), is a common denominator as seen from the Japanese survivors of the effects of radiation from the atomic bombing.
