| beta radiation |
Beta radiation is comprised of charged particles emitted from a nucleus during radioactive decay. A negatively charged beta particle is identical to an electron. A positively charged beta particle is called a positron. Beta radiation is slightly more penetrating than alpha, but it may be stopped by materials such as aluminum or Lucite panels. Naturally occurring radioactive elements such as potassium-40 emit beta radiation.

| beta |
A measure of a security's systematic or market risk. While most stocks move in in the same direction as the stock market, the level of the beta indicates the degree of correlation between a security and the market. The market is the benchmark and has a beta of 1.
