Abstract: Methods, apparatuses, and methods for manufacturing apparatuses that differentially detect beta and/or gamma rays are described. One radiation sensor described herein has operational amplifier(s), two blocking layers capable of blocking beta rays, and two photodiodes. The first photodiode is disposed between the blocking layers and thus isolated from incident beta rays. Accordingly, the first photodiode is capable of detecting gamma rays and providing a current corresponding to detected gamma rays to an operational amplifier. The second photodiode is disposed on one of the blocking layers and is capable of detecting beta rays and gamma rays and providing current corresponding to detected beta and/or gamma rays to an operational amplifier. The operational amplifiers convert the currents into voltage pulses which are used to, for example, determine if beta and/or gamma rays are detected and the amount/level of detected rays.
