Gamma Decay

Some articles on gamma, decay, gamma decay:

Gamma Ray
... Gamma radiation, also known as gamma rays or hyphenated as gamma-rays and denoted as γ, is electromagnetic radiation of high frequency and therefore high energy ... Gamma rays are ionizing radiation and are thus biologically hazardous ... They are classically produced by the decay from high energy states of atomic nuclei (gamma decay), but are also created by other processes ...
Radioactive Source - Types of Decay
... The rays were given the alphabetic names alpha, beta, and gamma, in order of their ability to penetrate matter ... While alpha decay was seen only in heavier elements (atomic number 52, tellurium, and greater), the other two types of decay were seen in all of the elements ... Spontaneous decay is evident in elements of atomic number ninety or greater ...
Properties - Gamma Ray Production - Radioactive Decay (gamma Decay)
... Gamma rays from radioactive gamma decay are produced alongside other forms of radiation such as alpha or beta, and are produced after the other types of decay occur ... It can then move to a lower energy state by emitting a gamma ray, in much the same way that an atomic electron can jump to a lower energy state by emitting a photon ... Emission of a gamma ray from an excited nuclear state typically requires only 10−12 seconds, and is thus nearly instantaneous ...

Famous quotes containing the word decay:

    The goal of every culture is to decay through over-civilization; the factors of decadence,—luxury, scepticism, weariness and superstition,—are constant. The civilization of one epoch becomes the manure of the next.
    Cyril Connolly (1903–1974)
