摘要:
A dosimetry method exposes more than one thermoluminescence crystals to radiation without using conventional filters, and reads the energy stored in the crystals by converting the energy to light in a conventional manner, and then filters each crystal output in a different portion of the spectrum generated by the crystals.

The invention includes a temporal dosimeter. One dosimeter embodiment includes a housing that is opaque to visible light but transparent to ionizing radiation. The dosimeter also includes a sensor for recording dosages of ionizing radiation, a drive mechanism, a power source, and rotatable shields that work together to produce a compound aperture to unveil different portions of the sensor at different times to ionizing radiation. Another dosimeter embodiment includes a housing, a sensor, a shield with an aperture portion, and a linear actuator drive mechanism coupled to the sensor for moving the sensor past the aperture portion. The sensor turns as it moves past the aperture, tracing a timeline record of exposure to ionizing radiation along a helical path on the sensor.

Disclosed are a CaSO4 based TL detector bonded with phosphorous compound and a method for fabricating thereof. The CaSO4 based TL detector can be fabricated by mixing CaSO4 based TL powder with a phosphorous precursor; molding the mixture powder under pressure; and sintering the molded body. The TL detector has so high TL sensitivity as to effectively measure personnel dose equivalent and low dose detection. It can be also manufactured in various forms and is easily handled, finding numerous applications in personnel and environmental monitoring fields.
