Detector for measuring radioactivity in a sample, the detector being configured to operate at a cryogenic temperature and comprising a crystal absorber (10), in which a cavity (11a; 15) is formed, tor receiving a sample (B) whose radioactivity is to be measured, said, crystal absorber (10) being configured to produce phonons in response to an interaction of an ionizing radiation with the crystal absorber (10), at least one thermal sensor (20; 21, 22; 23, 24) configured to detect a variation in the temperature of the crystal absorber (10) in response to a. production of phonons in the crystal absorber (10), and electronics (100) configured to determine the energy deposited by the ionizing radiation in the crystal absorber (10) as a function of said temperature variation.
