WebThoron has a half-life of only 55 seconds, which mostly results in low levels indoors (1). Recent measurements in some countries have shown, however, that in certain situations the doses from thoron and its progeny are significant and comparable to those from radon (2–4). Radon decays into radioactive metal ions by alpha radiation. WebBruce K Thorn is President/CEO at Big Lots Inc. See Bruce K Thorn's compensation, career history, education, & memberships.
