The radiometer is a device that measures the intensity of refulgent energy. He later invented the vacancy tube which is the precursor of the roentgenogram tube.

Beginning in 1887, he began investigating electrical charges by highly evacuated Crookes Tubes. His trim led to the foundation of J. J. Thomsons search in the 1890s on the discharge-tube phenomena. afterward in his li fe, at the age of 68, Crookes began to inves! tigate the phenomenon of radioactivity. irradiation had been discovered in 1896, and Crookes invented a device that would notice alpha particles emitted from the radioactive material.
