6 days ago · While radioactive materials and X-rays were once handled carelessly, increasing awareness of the dangers of radiation in the 20th century led to the implementation of various preventive measures worldwide, resulting in the establishment of radiation protection regulations.
3 days ago · List of radioactive nuclides by half-life. This is a list of radioactive nuclides (sometimes also called isotopes ), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds. [1]
2 days ago · When Voyager 1 is unable to communicate with the Earth, its digital tape recorder (DTR) can record about 67 megabytes of data for later transmission. As of 2023 [update] , signals from Voyager 1 take more than 22 hours to reach Earth.
5 days ago · The Science. For the first time, nuclear physicists made precision measurements of a short-lived radioactive molecule, radium monofluoride (RaF). The researchers combined ion-trapping techniques with specialized laser systems to measure the fine details of the quantum structure of RaF.
5 days ago · Radioactive molecules containing octupole deformed nuclei, such as radium (Ra), promise to be exceptional quantum systems for use in studies of the fundamental particles and forces of nature.
5 days ago · Radiology is the field of medicine that uses imaging techniques such as X-rays to diagnose, characterize, or monitor disease. Medical doctors who specialize in radiology are called radiologists. Radiology can provide evidence of an injury, infection, or disease that cannot be seen without an invasive procedure.
5 days ago · The highly unstable radioactive element promethium is hard to study in the lab, but chemists have now coaxed it into forming a compound in water so they can observe its bonding behaviour
