Resumo
The use of different types of radiation is being increasingly widespread in various
human activities such as in several industrial and nuclear technologies, where
high radiation doses are involved, while in medicine usually low doses are
involved. The radiation, on the other hand can be harmful to human being so that
gamma and neutron radiation dosimetry becomes very important. There exist
different detectors systems in radiation dosimetry but that based on the
thermoluminescent crystals being one of the most important. For example, LiF
based LiF:Mg,Ti (MTS) and LiF:Mg,Cu,P (MCP) that proved to be good detectors
for gamma-rays, neutrons and other radiation [1]. On the other hand, natural
silicate minerals proved to be very sensitive TL materials. In our laboratory
several natural silicate minerals have been investigated, among them, the green
quartz was proved to be very sensitive dosimeters both for low (mGy) and for high
and very high radiation doses (kGy-Mgy) [2]. In this work, we produced in the
laboratory polycrystals of CdSiO3 and CaSiO3. With respect to CaSiO3 we
produced polycrystals doped with Eu, Dy, Cd and B. CaSiO3 doped or not has
shown to be excellent detectors of gamma-rays as well as of neutrons produced in
a research reactor (reactor IEA-R1 from Institute for Energy and Nuclear
Research). CdSiO3 presented a TL peak at low temperature, therefore is unstable,
while all CaSiO3 detectors have shown an excellent behavior.
