Radioactive decay

Frederic Joliot is not a common household name yet with the knowledge gained; from his research, we can now properly understand the structure of the radioactive atoms that help power substations today. It is an honor to write about this once famous physicist-chemist because his early life inspired others to finish strong. Joliot's Was the son of Henri Joliot, a merchant, and Emilie Roederer. Joliot was born on 19th of March 1900, in Paris, France while he entered life with a weak leg up on the privilege

medicine, wherein radioisotopes are taken internally (via radiopharmaceuticals) and the emitted radiation is captured by external detectors (gamma cameras) to form two-dimensional images. What is Technetium-99m? Technetium-99m is a widely used radioactive tracer isotope in Nuclear Medicine. Its gamma ray energy of about 140 keV is convenient for detection. The fact that both its physical half-life and its biological half-life are very short leads to very fast clearing from the body after an imaging

Nuclear imaging (also known as nuclear medicine) is an imaging modality that involves injection, inhalation or injection of radioactive radiopharmaceuticals to visualize various organs and tissues. However, not only organs and tissues can be monitored, but also particular cells that are directly (for example with F-FDG tracer) or genetically (for example with HSV1-tk reporter gene) labeled . In order to use this nuclear imaging modality radiopharmaceuticals (also called tracers) are given internally

Radiation Therapy In 1896, German physics professor Wilhelm Conrad Roentgen, produced and detected electromagnetic radiation in a wavelength known as the x-ray. Within three years of his discovery, radiation became used to treat cancer after Henri Bacquerel discovered radium’s ability to kill skin cells due to its radioactivity. The first person to experiment with cancer cells was Henri Danlus, a French doctor. Pierre Curie simultaneously researched and experimented with cancerous cells, and both

time, which can be within a few days or a few thousands of years, Carbon 14 can decay back into nitrogen. Since Carbon 14 is produces at a steady rate, it is constantly in the environment, at a steady level. There are trillions of carbon atoms in our body but only a dozen of them are Carbon

we obtain by adding up the masses of all the protons and neutrons. This is the binding energy. The nucleus of an atom determines if it is stable or unstable. The higher the binding energy, the more stable an atom is. Unstable nuclei are radioactive, where they decay until they form stable nuclei. They emit different particles to form more stable daughter nuclei.

2.3 β-particle emission radionuclides Β-particles are high energy electrons which are ejected from the nucleus with a range of energies up to a maximal value.12 β-emitters are heavily researched and are a widely accessible form of radionuclide therapy. The LET of β-emitting particles is high enough to kill cancerous cells, but is considered low compared to α-emitters which have a lot more particles in the higher energy levels. Β-particle emitters deposit their energy over a much larger range (1mm

you, your family and even your home. But, the only way you'd ever even worry about radon is by learning about it and seeking professional assistance. Radon is an invisible, odorless, hazardous and natural occurring gas that is a result from uranium decay in the earth's crust. In the United States, radon is the leading cause of cancer found amongst non-smokers. Radon is dangerous because it quickly breaks down and scatters into the air. Large and dangerous amounts of radon can and will accumulate inside

Carbon is a light atom with 6 protons and usually 6 neutrons in its nucleus. Sometimes Carbon can contain 8 neutrons but in that form the nucleus is unstable. With the nucleus being unstable, the element falls apart through radioactive decay. This rate of decay is consistent over long periods of time. Because this certain type of carbon (Carbon-14) is in many materials, measuring the amount of carbon-14 in that material lets us figure out that material’s age. This is known as carbon dating.
