Abstract

Kendaraan CBRN (Chemical, Biological, Radiological, and Nuclear) didesain untuk beroperasi dalam kondisi lingkungan berbahaya dan penuh risiko sehingga personel yang mengoperasikannya atau bekerja didalamnya harus dilindungi dari potensi bahaya CBRN, khususnya dari bahaya radiasi sinar gamma. BRIN bekerja sama dengan PT Pindad mengembangkan desain prototipe kendaraan taktis CBRN dengan bodi berbahan armour. Penelitian ini bertujuan untuk menganalisis keselamatan personel di dalam kendaraan taktis CBRN dengan bodi berbahan armour baja Secure 600 setebal 8 mm terhadap laju dosis serap efektif radiasi gamma yang dipancarkan Co-60 atau Cs-137 dengan cara pemodelan dan simulasi menggunakan code MCNPX. Hasil simulasi berupa nilai laju dosis serap efektif detektor yang dipasang di beberapa titik menggunakan tally F5 MCNPX di dalam kendaraan dan hasilnya dibandingkan dengan nilai batas dosis untuk pekerja radiasi. Secara umum dinding kendaraan taktis CBRN dari baja Secure 600 setebal 8 mm untuk kuat sumber Co-60 atau Cs-137 sampai 1 mCi menghasilkan laju dosis aman, sedangkan untuk kuat sumber di atas 1 mCi tidak aman bagi personel di dalam kendaraan CBRN. Penemuan ini sangat penting dalam desain dan pengembangan kendaraan taktis CBRN yang memberi perlindungan maksimum bagi personel di dalamnya terhadap paparan radiasi sinar gamma.

Abstract

Experiments on making a plastic scintillator with polystyrene as a base material mixed with fluorescent compounds (primary and secondary dopants) have been performed. Primary dopants (PTP) used to produce emission at wavelengths of visible light and secondary dopants (POPOP) to shift the visible wavelengths to wavelengths that could be detected by Photomultiplier Tube (PMT) ) were carried out. Experiments were performed on the melting points condition of these materials, which had previously been subjected to a thermo-mechanical analysis using a Thermogravimetric Analysis-Differential Scanning Calorimetry (TGA-DSC) machine, where the melting point was in the range of 200-240°C. Furthermore, the fabrication was carried out using the extrusion technique, where polystyrene pellets mixed with PTP (1.5% by weight) and POPOP (0.05% by weight) were fed into an extrusion machine which has four hot areas to obtain a thin plate plastic scintillator. The plates were then analyzed with a UV-Vis Spectrophotometer to determine the absorption spectrum and Fluorescence Spectrophotometer to determine the emission spectrum. From the results of the analysis, it was found that the samples that went through scintillation pellets and without the addition of antioxidants had absorption spectrum data of 330 nm and emission spectrum of 421 nm. These values are in accordance with the characteristics of plastic scintillators on the market.
