In the dental setting the main concern is the dental radiation effects on children. Panoramic dental x-rays can cause DNA damage and cellular death in oral mucosa cells of these children. Cone-beam CT scanner, which was claimed to be the safe, is harmful on children due to them being more susceptible to radiation effects. Children are by far more susceptible to changes in their cells from a given dose of radiation compared to adults because they are still growing, developing, and changing. Radiation protection is needed to protect all children and adults from the exposure, the less the exposure the less problems later in life.
Children are more susceptible to changes in their cells if given adult doses of radiation. Primary risks to children from these scans are increased risks in them developing cancer and changes to their genes in later life. There was a study done in Brazil at the Sao Paulo Metodista University, which consisted of 17 healthy children. 8 of the children were boys and 9 of them were girls, around 7 years of age who had had panoramic dental radiographs as outpatients at the Department of Pediatrics. All the panoramic dental radiographs were requested and performed by the dentist. This study was approved by the Human Ethics Committee of UMESP. Prior to the x-ray exposure oral mucosa was collected and then 10 days after the exposure from the x-rays they were collected again. After the oral mucosa is collected post exposure to x-rays the levels of radiation were tested showing very little effect change. The statistics of this study are, prior to exposure 17 children had micro nucleated cells of 0.04-0.06 and after the exposure to the x-rays they were 0.05-0.06 cells that were micro nucleated. Very little change show...

... when the settings were put at the pediatric levels, as so they should. Protection is one of the most key things to do when protecting any patient from radiation exposure. The lead vest, lead neck collars, settings of the radiation set to each patient rather than a random setting, and the abilities as the dental assistant to be competent enough to take the set of x-rays the first time without needing to expose your patient numerous times.

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
In 1895, Professor Wilhelm C. Roentgen, a German physicist, was working with a cathode ray tube, much like our fluorescent light bulb. The tube consisted of positive and negative electrodes encapsulated in a glass envelope. On November 8, 1895, Roentgen was conducting experiments in his lab on the effects of cathode rays. He evacuated all the air from the tube and passed a high electric voltage through it after filling it with a special gas. When he did this, the tube began to give off a fluorescent glow. Roentgen then shielded the tube with heavy black paper and discovered a green colored fluorescent light could be seen coming from a screen located a few feet away from the tube.
The role of the radiologist is one that has undergone numerous changes over the years and continues to evolve a rapid pace. Radiologists specialize in the diagnoses of disease through obtaining and interpreting medical images. There are a number of different devices and procedures at the disposal of a radiologist to aid him or her in these diagnoses’. Some images are obtained by using x-ray or other radioactive substances, others through the use of sound waves and the body’s natural magnetism. Another sector of radiology focuses on the treatment of certain diseases using radiation (RSNA). Due to vast clinical work and correlated studies, the radiologist may additionally sub-specialize in various areas. Some of these sub-specialties include breast imaging, cardiovascular, Computed Tomography (CT), diagnostic radiology, emergency, gastrointestinal, genitourinary, Magnetic Resonance Imaging (MRI), musculoskeletal, neuroradiology, nuclear medicine, pediatric radiology, radiobiology, and Ultrasound (Schenter). After spending a vast amount of time on research and going to internship at the hospital, I have come to realize that my passion in science has greatly intensified. Furthermore, both experiences helped to shape up my future goals more prominently than before, which is coupled with the fact that I have now established a profound interest in radiology, or rather nuclear medicine.
Bitewing radiographs are an important adjunct to clinical examination and maybe necessary to help the clinician detect and diagnose caries (REF). However ionising radiation from x-ray exposure has the potential to cause malignancy in the patient and therefore clin...
...b done but can bring more side effects to the patient. Radiation is a connection to physics, which was a very important important discovery in science because it has cured many patients who have been affected by cancer when before they were left to die. Radiation therapy, like any other way exposed to radiation, can be a risk. The importance of undergoing this treatment is to see the positive side of it, not just think of the bad things that can come out of the radiation therapy. There is a risk of second cancers but isn’t it worth it? This treatment gives patients the chance to live a longer and normal life, this wasn’t an option before, so it’s important to be thankful for being born in this time period. Radiation might not be seen as a good thing in many occasions but it is now used for the good of the people affected by cancer, it’s a second chance for life.
Many of the experts agree that the dose should be kept as low as possible with minimal exposure to the fetus of any age. It has been shown that fetuses before 16 weeks are the most sensitive to any dose of ionizing radiation and have been shown to have lower IQ’s and verbal scores than those exposed after 16 weeks. Fetuses exposed after 16 weeks have the same amount of risk as children up to 10 years old getting cancer. It is very important to take in to consideration gestational age, shielding, the position of the x-ray tube and the amount of necessity that is considered in taking a radiographic image or performing a radiographic procedure in a pregnant woman.
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.

When taking a radiograph there are some precautions that can be taken to reduce some of the radiation that can be exposed to a patient, what would be used on all patients is call a lead apron and thyroid collar, these aprons are used to protect the patients that may be a bit more radiosensitive and also may give the patient a little of reassurance that they will be protected. “Radiosensitivity is the relative susceptibility of cells, tissues, organs, organisms, or other substances to the injurious action of radiation.”
...ontamination methods and permit training people in radiological safety and decon procedure. When the troops of operation crossroads returned to Pearl Harbor many of them became sick the doctors could not figure out why. Some of them died a slow death from the radiation that they were exposed to during the operation.
...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.
The energy in ionizing radiation can cause chemical changes in the the cells that can lead to damaging them. Most of the cells can either permanently or temporarily become abnormal or they can just die. Radiation can cause cancer by damaging the DNA in the body. The damage of the cells can also depend on how long the organs are exposed (environmental protection agency, 2017, unknown). If someone has many exposures at one time that radiation in the body keeps adding on. As well as if its only a little bit of exposure in on day and years later you get exposed again it keeps adding on the radiation will never leave the body. Having radiation in your body doesn’t affect you right away but as you get older it starts to show and you feel it. Chronic exposure is when someone is exposed many time for long periods. When this happens the type of effects it will carry is having harmful generic change, cancer, tumors, and even cataracts. Partial health effects can also depend on if it was internal or external exposure. Internal exposure is when either by drinking, breathing, eating and even an injection cause radiation to get inside your body. External exposure is when taking an x-ray out of your body and letting it go through letting all the energy go as it goes in (environmental protection agency, 2017, unknown). In the dental world radiation gets into the patients when we take x-rays on there teeth. In order to avoid to much radiation on them we put a lead apron on them and make sure to cover their thyroid which is the most common way of getting cancer when taking an x-ray. When we take the x-ray we stand behind a wall at least 6 feet away to avoid ourself from getting
A way to minimize the threat of radiation exposure, is to have proper shielding for those traversing inside the spacecraft. A lesson from the Curiosity Mars mission, is that having adequate. Shielding would enable a twelve month trip to and from Mars, only exposing the astronauts to two-thirds of a sivert (Gelling, 2013).... ... middle of paper ... ...malfunctions, and psychological problems brought on by isolation.
