Miniature spectrally selective dosimeter |
摘要 |
The present invention discloses a miniature spectrally selective dosimeter capable of measuring selected bandwidths of radiation exposure on small mobile areas. This is achieved by the combination of photovoltaic detectors, electrochemical integrators (E-cells) and filters in a small compact case which can be easily attached in close proximity to and substantially parallel to the surface being measured. In one embodiment two photovoltaic detectors 13 and 8, two E-cells 15 and 9 and three filters 14 and 16 are packaged in a small case 17 with attaching means consisting of a safety pin 19. In another embodiment, two detectors 31 and 32, one E-cell 33 and three filters 34 and 35 are packaged in a small case 36 with attaching means consisting of a clip 37 to clip over a side piece 38 of an eye glass frame 39. In a further embodiment, the electro-optic elements are packaged in a wristwatch case 51 with attaching means being a watchband 52. The filters in all embodiments allow only selected wavelengths of radiation to be detected by the photovoltaic detectors and then integrated by the E-cells.
