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

BATAN has the authority to improve the quality of lead brick production, which is still fabricated conventionally. Therefore, a non-destructive testing system has been developed, consisting of a Partial Immersion Technique transducer used to maintain a perpendicular scanning angle due to the uneven surface of the lead brick, an un0rick board used for its flexibility and good capability in generating high-voltage electrical pulses and high sampling frequency, and a laptop. The result is the optimization of ultrasonic parameters, with a transducer frequency of 500 KHz and a pulse length of 0.5 μs. Additionally, tests were conducted on three cases. A standard lead brick used as a reference has a propagation speed of 2.156 m/s. The lead brick with artificial defects had the first defect location estimated at 23.32 mm with an error of 16.62%, the second defect location estimated at 25.1 mm with an error of 0.44%, the third defect location estimated at 36.17 mm with an error of 9.57%, and the fourth defect location estimated at 9.38 mm with an error of 6.2%. The third case, a lead brick with natural defects, had the defect location estimated at 26.77 mm with an error of 1.08%.
