A noise dosimeter with capability to rapidly predict noise exposure over an extended time period based on a measurement of short duration. Either an acoustic or an electrical earphone adapter provides a convenient means to connect the noise dosimeter to an external sound source. A direct input jack operable to receive at least one audio signal provides a signal to an RMS detector, which provides a DC signal to a two-stage amplifier circuit. The outputs of the amplifiers are provided to a processor having multiple A/D channels. The processor calculates accumulated noise doses and drives a display, which in one embodiment includes a panel of light-emitting diodes. In one embodiment, the dosimeter includes functionality for control of external devices such as sound boards.

Provided are a gamma ray detector and a gamma ray reconstruction method which can be used in SPECT and PET and which combine and reconstruct the information on “Compton-scattered” gamma rays, thereby remarkably increasing gamma ray detection sensitivity, decreasing the amount of a radioactive substance given to a subject, and remarkably reducing the concern about the amount of radiation exposure. The gamma ray detector comprises an absorber scintillator 12 made from an absorptive substance exhibiting a high rate of absorption with respect to gamma rays 1 in an energy region, emitted from a subject, a Compton scattering scintillator 14 made from a Compton scattering substance exhibiting a high probability of Compton scattering, and an energy detector 16 which combines the amounts of gamma ray energy absorption simultaneously measured by the two types of scintillators to reconstruct the gamma rays emitted from the subject. The two types of scintillators 12 and 14 are arranged in multiple layers so as to absorb or Compton-scatter the whole energy of the gamma rays 1.
