Ionizing radiation

They compared their findings with 200,000 people that were not exposed to the atomic bomb. The researchers found that exposure to the bomb's radiation increased the survivors' risk for cancer by about 10 to 44 percent but on average, they lived only a few months shorter than the people who were not exposed to the radiation. The findings likewise showed no radiation-associated mutations in the survivors' children…

Radiation therapy uses high doses of radiation to kill cancerous cells and is sometimes used as a substitute for surgery, destroying or shrinking a tumor. Even though radiation therapy can save lives and prevent recurrence of cancer, healthy cells that are exposed to the radiation may develop into a new cancer (Radiation, 2014). Radiation can be internal or external. Internally, radiation is put inside the body near or in the cancer cells. Externally…

A brain tumor or intracranial neoplasm occurs when abnormal cells form within the brain. There are two main types of tumors: malignant or cancerous tumors and benign tumors. Secondary or metastatic brain tumors are more common than primary brain tumors, In children younger than 15, brain tumors are second only to acute lymphoblastic leukemia as a cause of cancer. In Australia the average economic cost of a case of brain cancer is $1.9 million, the greatest of any type of cancer. Signs and…

These radioactive elements decay spontaneously into different elements while also releasing ionizing radiation from the nuclei. The radiation most commonly emitted from these radioactive elements are alpha (α) particles, beta (β) particles, and gamma rays (γ). An alpha particle consist of two protons and two neutrons, in which upon release decreases the atomic radii…

Kacee McDaniel During your pregnancy you should try to stay away from teratogens. The Healthline Editorial Team wrote that pregnant women should not be exposed to excessive heat, herbal treatments, ionizing radiation, sick children, or toxoplasmosis, which is an infection contracted from cat feces to humans. There is also a list of ingestible teratogens that pregnant women should stay away from such as, alcohol and certain types of drugs, like Warfarin and Dilantin (Healthline Editorial…

structure or when an uncomplimentary base is found in the DNA. As a result there are different amino acids which can stop the codon. Mutation can form because of natural causes such as ultraviolet radiation from the sun. However they can also occur due to environmental factors , such as chemicals or ionizing radiation. There are many ways that DNA can mutate such as substitution this is a mutation that exchanges one base for another. For example a change in a single molecule or switching an…

corned beef had been treated with radiation in order to kill any harmful microorganisms that might have been present in the canned meat. Since its accidental discovery, D. radiodurans has been intriguing scientists with is astonishing resistance to ionizing radiation, UV radiation, electrophilic mutagens, oxidizing agents, and desiccation. This gram-positive bacteria usually forms in spherical pairs or tetrads; it is not only able to survive gamma radiation greater than 2,000 DSBs (per…

done this by first going so far as to increase the peoples limit for radiation…

which X-ray machines utilize ionizing radiation to take images of patients’ bones throughout their bodies that may or may not be broken. The image is then sent to a Radiologist who analyzes and diagnoses the image and sends the results to the doctor. As a technologist you must be able to effectively operate the X-ray machines, correctly position patients, interact with them to make them feel comfortable while always staying as protected as possible around the radiation that both the technician…
