Radioactive decay

The first woman to win a noble prize for not just Physics but Chemistry too, would have a dramatic impact on the world as we know it today. Marie Salomea Sklodowska was a polish scientist, born on November 7, 1867 in Warsaw, Congress Kingdom of Poland, Russia. Marie’s mother, Bronislawa, and father, Wladyslaw, were both teachers and wanted Marie to have an education. During school when Marie became fascinated with the art of science Marie’s parents were extremely encouraging and supportive.…

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,…

which emits gamma radiation are injected into the human body, then; the system detects pairs of gamma rays emitted indirectly by a tracer to show images of bones and organs. These substances are injected into the body, and are usually tagged with a radioactive atom.[1] Doctors use this device to create images of bones and organs of the patients. They take many pictures from different angles, and; use a computer software to create a full three-dimensional image of the particular body part. The…

Radio isotopes: The help and the hurt Radio isotopes are used constantly in the medical and industrial world. They can be useful when diagnosing human and other animals with diseases, and in treating them for many diseases. However, the use of radioisotopes can increase the demand for nuclear power, and have many negative side effects on humans and other organisms. Many radio isotopes are relatively harmless in the body. They can be used to view the inside of your body, allowing doctors to…

Electromagnetic waves are a type of radiation that is produced from electrons (negatively charged particles) and x-rays is a type of electromagnetic wave. The shorter the wavelength of a wave, the more energy the wave emits. Gamma radiation has the shortest wavelength amongst all the other electromagnetic waves and has the most energy. It cannot be seen or felt and can pass through almost anything. X-rays have slightly longer wavelengths than Gamma rays and has the second most energy emission.…

Introduction Radiation protection policy is distributed among several governmental Agencies in the United States. Each agency is tasked with controlling exposure to radiation and the safe use of radioactive materials and radiation generating devices. These agencies inform their policy with reports and recommendations from a number of organizations, including the National Council on Radiation Protection and Measurements (NCRP). The NCRP is a longstanding organization that strives to provide…

discovered that only certain chemical elements gave off these rays of energy and named this radioactivity. Although Becquerel called this radioactivity, Curie later coined the term “radiation”. She’d be the first to work with radioactive materials and also later discover other radioactive elements such as thorium, polonium, and radium. In 1901 within months of studying and experimenting, systems were being made to use x-rays for diagnosis, and within 3 years radiation was used in to treat…

Radiation Burns A burn is an injury caused by an excessive amount of heat. It damages the skin, causing tissue destruction. There are four types of burns; thermal, chemical, electrical, and radiation burns. Someone might get a radiation burn if they are overexposed to industrial ionizing radiation or after doing a radiotherapy treatment. Burns Radiation burns will most likely happen to cancer patients during their radiation treatment or radiotherapy. A response can…

Radiation is defined as emission of energy in the form of x rays and gamma rays. It is transmitted from one place to another. Ionizing radiation is high energy waves that pass the body's tissue, that produces positive and negative charged particles. These high energy waves remove electrons from atoms and cause an interaction between the x rays and the patient. This process is referred to as ionizing radiation. The amount of energy acquired from ionizing radiation is absorbed into the patients…

Strontium Isotope ratios are used in archaeology to track human migration.86Sr abundance is constant, but 87Sr forms through decay of 87Rb in rock. Rock age and initial Rb/Sr ratios vary geographically, making87Sr/86Sr a location tracer. Strontium, weathered from bedrock into groundwater then taken up by flora and fauna, can substitute for Ca in tooth enamel. Enamel only forms during childhood, specifically the early first and second molars mineralize during early childhood; the third molar…
