WebbThree main types of nuclear decay have been identified: alpha, beta, and gamma. Alpha decay occurs when a nucleus splits into two parts: a helium nucleus and the remainder of the original nucleus. Beta decay occurs when a neutron in the nucleus of an element changes into a proton. Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay … Visa mer Radioactivity was discovered in 1896 by scientists Henri Becquerel and Marie Skłodowska-Curie, while working with phosphorescent materials. These materials glow in the dark after exposure to light, and he … Visa mer The International System of Units (SI) unit of radioactive activity is the becquerel (Bq), named in honor of the scientist Henri Becquerel. One Bq is defined as one transformation (or … Visa mer The decay rate, or activity, of a radioactive substance is characterized by the following time-independent parameters: • The half-life, t1/2, is the time taken for the activity of a given … Visa mer The radioactive decay modes of electron capture and internal conversion are known to be slightly sensitive to chemical and environmental effects that change the electronic structure … Visa mer The dangers of ionizing radiation due to radioactivity and X-rays were not immediately recognized.

Webb24 feb. 2016 · In same way if somehow we can move radioactive substance faster than we will be able to expand the period of radioactivity. We know the relation, T=0.693/ λ ,where T is half life and λ is the decay constant. So as we move faster through space literally we move slower in time resulting change in value of λ.
