The radiological protection of professionals and patients is nowadays of paramount importance.
There is an annual dose limit set by Euratom directives for professionals and patients which, if not exceeded, allows safer use and has low impact on the health of those involved.
Real time monitoring of radiation in interventional cardiology allows better control of the delivered dose which might be critical in long interventions. This can be achieved with the use of active dosimeters.
In this work a real time device for the measurement...
Description of activity and work performed
The developed dosimeter consists of a BC-404 scintillator (from Saint-Gobain), 10 mm long and 2 mm in diameter, connected to a SK-80 optical clear fiber. The signal produced in the scintillator is read by a R647P photomultiplier (PMT) from Hamamatsu. The output of the PMT is feed to an integrated amplifier MTI04CS produced by MaZeT. The output signal from the amplifier is digitized by an Arduino UNO microcontroller. The acquisition system is based on a Raspberry Pi microprocessor. During the testing phase a simple...
Conclusion and recommendations
In this study a linear relation between the signal produced by the developed scintillator dosimeter and dose measured by a Farmer ionization chamber was found. The transparency of the scintillator dosimeter allows its use for patient monitor in interventional cardiology.
