It is radioactive and exhibits strong yellow fluorescence under ultraviolet radiation.Ulrichite was first described in 1988 for samples from the Lake Boga granite quarry Lake Boga Victoria Australia. It was named for George H. F. Ulrich (1830–1900) a 19th-century government geologist and mines department inspector.
