Abstract

An apparatus for detecting particles from radioactive decay, such as alpha particles, has a first detector circuit (101) and at least a second detector circuit (102) adapted to generate a respective electric signal on a respective output (111, 112) for indicating a hit by a radioactive particle. A controller (140) is operatively coupled to the output of the first and second detector circuit, respectively. The controller provides a result output indicative of a number of radioactive particle hits as indicated by the first and second detector circuits. Moreover, the controller ignores any second particle hit, which follows after a first particle hit, if the first and second particle hits are indicated within a time period, which is shorter than a predetermined time period.
