Radiobiology (also known as radiation biology) is a field of clinical and basic medical sciences that involves the study of the action of radioactivity on biological systems. The controlled action of deleterious radioactivity on living systems is the basis of radiation therapy.
The ICRP 2007 standard values for relative effectiveness are given below. The higher radiation weighting factor for a type of radiation, the more damaging it is, and this is incorporated into the calculation to convert from gray to sievert units. The radiation weighting factor for neutrons has been revised over time and remains controversial.
Nuclear Medicine and Biology is a peer-reviewed medical journal published by Elsevier that covers research on all aspects of nuclear medicine, including radiopharmacology, radiopharmacy and clinical studies of targeted radiotracers. It is the official journal of the Society of Radiopharmaceutical Sciences.
Ionizing radiation is generally harmful and potentially lethal to living things but can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis. Its most common impact is the induction of cancer with a latent period of years or decades after exposure.
Marie and Pierre Curie's study of radioactivity is an important factor in science and medicine. After their research on Becquerel's rays led them to the discovery of both radium and polonium, they coined the term "radioactivity" [ 13 ] to define the emission of ionizing radiation by some heavy elements. [ 14 ] (
Applied Radiation and Isotopes is a peer-reviewed scientific journal published by Elsevier. It was established in 1993 and its scope covers applications of ionizing radiation and radionuclides. [1] The current editors-in-chief are Richard P. Hugtenburg (Swansea University) and Denis Bergeron (National Institute of Standards and Technology). [2]
Radiation exposure can be managed by a combination of these factors: Time: Reducing the time of an exposure reduces the effective dose proportionally. An example of reducing radiation doses by reducing the time of exposures might be improving operator training to reduce the time they take to handle a radioactive source.
Nuclear medicine (nuclear radiology, nucleology), [1] [2] is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear imaging is, in a sense, radiology done inside out , because it records radiation emitted from within the body rather than radiation that is transmitted through ...
