self-irradiation

The local doctor, unaware of the men's self-irradiation, becomes convinced that a recent change in South Park is responsible for the cancer outbreak.

Interconversions between the three phases can occur spontaneously, as a result of self-irradiation or self-heating.

The self-irradiation occurs as the plutonium undergoes alpha-decay.

Self-irradiation can also lead to annealing which counteracts some of the fatigue effects as temperature increases above 100 K.

Metallic plutonium, notably in the form of the plutonium-gallium alloy, degrades chiefly by two mechanisms: corrosion, and self-irradiation.

Because of self-irradiation, a sample of plutonium fatigues throughout its crystal structure, meaning the ordered arrangement of its atoms becomes disrupted by radiation with time.

At cryogenic temperatures, where next to no annealing occurs, the α-phase of plutonium expands (swells) during self-irradiation, the δ-phase contracts markedly, and the β-phase contracts slightly.

From 1997 to 2002 a series of published papers suggested that the self-irradiation of the lava would convert all 1,200 metric tons into a submicrometer and mobile powder within a few weeks.

The crystal lattice of solid americium and its compounds contains small instrinsic radiogenic defects, which are induced by self-irradiation with alpha particles and accumulate with time; this results in a drift of some material properties.

Heating the Am(IV) solution to 90 C did not result in its disproportionation or reduction, however a slow reduction was observed to Am(III) and assigned to self-irradiation of americium by alpha particles.
