Plutonium (V) fluoride is a chemical compound consisting of the elements plutonium and fluorine . It has the formula PuF 5 and belongs to the fluoride class of substances . The compound consists of PuF 5 units and forms linear chains through fluorine bridges.
presentation
Laser irradiation of plutonium hexafluoride at a wavelength below 520 nm causes it to decompose into plutonium (V) fluoride and fluorine; if irradiation is continued, plutonium (IV) fluoride is obtained .
safety instructions
Classifications according to the CLP regulation are not available, although the chemical toxicity is known. The dangers based on radioactivity are important , provided that the amount of substance involved is relevant.
