The Existence of Radiation

- Radiation has existed throughout the entire existence of earth. Scientists did not know about radiation until very recently because radioactive materials look the same as non-radioactive materials. It was not until February of 1896, when a French scientist named Antoine Henri Becquerel did an experiment using naturally fluorescent minerals to study x-ray properties, which were discovered by Wilhelm Roentgen, that scientists became aware of the existence of radioactivity. Becquerel “exposed potassium uranyl sulfate to sunlight, and the uranium-bearing crystals were later exposed” The Discovery of Radioactivity....   [tags: Radiation, FRC, RPD]

What Is Radiation Therapy?

- What is Radiation Therapy. Radiation Therapy is one of the principal modalities that are used in the treatment of cancer (Frank, Long, Smith 2012, p. 467). What is cancer. Cancer is the uncontrolled growth of abnormal cells in the body. This uncontrolled growth of cells can over time develop into a tumor. Then, this tumor can continue to grow and cause problems, and even spread if it is left untreated. Cancerous cells are also called malignant cells. In this modality, high energy x-rays, gamma rays, and charged particles are the forms of radiation used to shrink the cancer cells (Lawrence, Ten Haken, pg.1)....   [tags: Cancer, Oncology, Ionizing radiation]

Radiation and Its Uses, Specifically in South Africa

- What is radiation. Radiation is energy that comes from a source and travels in the form of waves or high speed particles. Radiation is mainly released from atoms, which is the smallest particle of matter. When radiation is emitted, it excites the orbiting electrons in atoms and causes the electrons to vibrate, which emits the energy. There are two types of radiation, namely Ionizing radiation and non-ionizing radiation. Non- ionizing radiation has a low energy level and therefore cannot change the chemical properties of a substance that it is exposed to....   [tags: Ionization, Energy, Cancer]

- The Atomic Bomb and Radiation Radiation as a carcinogen was first established in December 1895 after Roentgen’s discovery of X-rays. In 1902, the first radiation induced cancer was reported emerging from an ulcerated area of the skin. By 1911, a large number of these such skin cancers were reported as well as the first report of leukemia occurring in five radiation workers (Little 2000). Following these discoveries, large-scale tumor induction studies were carried out in animal models over the following 30 years....   [tags: Weapons Health Science Papers]

Earth Is Constantly Bombarded With Enormous Amounts Of Radiation

- Earth is constantly bombarded with enormous amounts of radiation (Pethica, J. et al., 2010.) Of the solar energy that reaches the Earth, which is ~340 W/m^2, 29% will be directly reflected back into space by clouds, gases and small particles in the atmosphere, or bright surfaces such as snow or ice. Of the remaining 71%, 23% is absorbed by the atmosphere and the remaining 48% passes through to be absorbed by the Earth’s surface. Due to this intake of energy, for Earth to maintain a stable temperature, it has to release as much energy as it absorbs back out into space in a process called radiative cooling....   [tags: Greenhouse gas, Global warming, Climate change]

Radiation Therapy Plus Long Term Androgen Deprivation Therapy And Radical Prostatectomy

A direct comparison between them is very difficult because of the intrinsic limitations of the involved studies: most of them are based on retrospective series, and no good-quality RCT have answered this question. In our opinion, it’s very unlikely that the current lack of evidence coming from randomized clinical trials in this area will be fully resolved in the next years: choice of treatment in this setting relies too much on patient’s and physician’s perspective to be easily entrusted to chance, given the different implication...   [tags: Cancer, Prostate cancer, Metastasis, Oncology]

Carbon Dioxide Can Absorb Energy From Infrared Radiation

- Carbon dioxide can absorb energy from infrared radiation due to its structural qualities. Carbon dioxide absorbs incoming infrared photons, wherein the energy from the photons causes the carbon dioxide molecule to vibrate. This allows the carbon dioxide mole to give up this extra energy by emitting another infrared photon and once the extra energy has been removed by the emitted photon then the carbon dioxide molecule stops vibrating. Therefore, carbon dioxide molecules have the capacity to absorb and re-emit infrared energy, which is what allows it to be an effective greenhouse gas....   [tags: Carbon dioxide, Oxygen, Climate change, Infrared]
