Radiation

mesothelioma include surgery, radiation therapy and chemotherapy. In surgery a part of the abdominal tissue is cut out to remove the tumor. At times the doctor may also need to remove a lung or a portion of the diaphragm as per the requirement of the surgery. Radiation therapy, the second method, requires the application of high energy X-rays to shrink the tumor and kill the malignant cells. The rays may be applied from an external machine or by placing the radiation source directly to the…

Photoacoustic spectroscopy (PAS) is a tool to study thermal emission resulting from non-radiative relaxation followed by absorption of radiation. PAS was studied primarily by Alexander Graham Bell, John Tyndall, Wilhelm Rontgen and Lord Rayleigh in 1884. For the history of PAS, was not until 1975 that photoacoustic spectroscopy started to be used as a wide range of different applications. This technique provides the following main advantages over the known types of spectroscopy. The advantages…

hospital. Within three months of the explosion, thirty operators and firemen that were working on the plant were also killed (Chernobyl Accident 1986). After those three months, many more people died because of radiation poisoning and cancers that were developed. Acute Radiation Syndrome or radiation sickness affected one hundred and thirty four people and was the cause of death for twenty eight people (Chernobyl Accident 1986). How could something this drastic happen? It all started with a…

“I hope I don’t get exposed to a radiation.” I thought to myself as a Nuclear Medicine Technologist in the future. Because I would have to prepare radiopharmaceuticals, I would communicate with others, and I would have to remember a ton of things, these things would be challenging about being a Nuclear Medicine Technologist. To begin, having to prepare radiopharmaceuticals would be a huge challenge to me. Radiopharmaceuticals is a radioactive compound used for diagnostic and therapeutic purposes…

Treatments range from chemotherapy, hormone therapy, radiation therapy, targeted therapy or surgery. Chemotherapy is a treatment of chemical substances that contain one or more anticancer drugs. Hormone therapy is when antagonists, drugs such as Lupron, are used to too treat the cancer patient. Radiation therapy is when high energy waves, such as x-rays, are used to destroy cancer cells. Targeted therapy is when specific drugs are used to target specific genes or proteins to stop the cancer from…

and sperm (testicles). Most testicular cancers start in cells that make sperm. These cells are called germ cells. The two main types of testicular germ cell cancers are seminomas and nonseminomas. Seminomas grow and spread slowly and respond to radiation therapy. Nonseminomas grow and spread more quickly than seminomas. Testicular cancer affects the testicles and it can spread through the body but it’s curable. Symptoms Men with testicular cancer may experience a variety of symptoms or…

Adaptive Radiation and Species Diversification Through a common ancestor, species diverge into new populations which eventually adapt to their new environments and evolve to become their own sub species and then distinct species. This occurs through the process of adaptive radiation. The population of an ancestor species radiates outwards to different ecological niches. From there, these now separate populations adapt to their new habitats and resources in isolation. This gives them…

Natalie Caparelli Mrs.Stanton October 5, 2015 Is Nuclear Chemistry Worth The Risk? Pros and Cons of Nuclear Chemistry in Medicine Nuclear chemistry, along with its advantages, has many cons such as extended decay periods, emission of radioactive particles into the atmosphere, and negative side effects from its many medical uses. Radioactive particles vary in strength, alpha particles, for example, are able to pass through sheet of paper. On the other hand, gamma rays are about to pass through…

cancerous cells. The method of chemotherapy may involve delivering medicines through an intravenous (IV) system or through oral ingestion. Radiation Therapy – The radiation therapy of treatment for cancer entails the use of high-energy light waves to destroy the cancerous cells. The radiation therapy may be given from outside the body (external-beam radiation therapy) or with the use of implants…

Scientists use radiation in more forms than the average person realizes. With new technology these developments form new ways of living. Agriculture is not recognized as a big part in nuclear science. George de Hevesy was the first to practically use an isotope in 1911. We can thank him for the new advancements in fields of nuclear technology. The food you eat probably was altered using a form of neutron or gamma irradiation. Radioisotopes have changed the way we live, through all fertilizers,…
