Learn about nuclear decay reactions. Understand what nuclear decay reactions are, when radioactive decay occurs, and explore three types of...
Types of Radioactive Decay The famous physicists Marie Curie and Ernest Rutherford, among many others, discovered that radioactive decay results in positive and negative particles and neutral rays. Due to the different penetration characteristics, the three results were given the names alpha decay, be...
Radioactive decay, also known as nuclear decay or radioactivity, is a random process by which an unstable atomic nucleus loses its energy by emission of radiation or particle. A material containing unstable nuclei is considered radioactive.

42 Radioactive Decay and Half-Life 1. In beta decay, a neutron gives off a beta particle. In alpha decay, an alpha particle consisting of two protons and two neutrons is emitted. 2. The mass of the atom decreases because the atom loses two protons ...
Radon gas is a radioactive product of the decay of naturally occurring uranium in the Earth's crust. Groundwater entering a house through a home water-supply system might release radon indoors where it could be breathed. Petroleum-based Fuels. ...
It's potentially dangerous but can be stopped by a thin barrier. Beta decay releases an electron, and a neutron becomes a proton. This type of decay can also be stopped by a relatively thin barrier. Read Radioactive Elements & Decay | Overview & Examples Lesson ...

Radioactive wastes contain chemical elements having an unstable nucleus that will spontaneously decay with the concurrent emission of ionizing radiation. Sewage and Agricultural Wastes Sewage originates primarily from domestic, commercial, and industrial sources. In many developed countries, these wastes ...
