· JVASP-20299· PuBe13

PuBe13 is a plutonium-beryllium ceramic compound, primarily of research and specialized nuclear applications rather than conventional engineering use. This material belongs to the intermetallic/ceramic family of actinide compounds and is notable for its neutron emission properties when plutonium undergoes alpha decay in the beryllium matrix, making it historically significant in nuclear weapons design and neutron source applications. Due to its extreme toxicity, radiotoxicity, and regulatory restrictions, PuBe13 is encountered only in nuclear research, legacy weapons stockpile management, and advanced materials science contexts—not in commercial or standard industrial engineering.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
