چکیده
ABSTRAKPerisai radiasi dengan nilai koefisien atenuasi linier tinggi dan harga bahan yang ekonomis menjadi pertimbangan dalam pengembangan perisai radiasi. Bahan berpotensi untuk dikembangkan adalah pasir besi batu apung. Dalam penelitian ini dilakukan investigasi pengaruh variasi komposisi campuran agregat besi-batu apung terhadap densitas serta ketebalan beton kemampuannya menyerap sinar-x. Pengujian menggunakan berkas foton LINAC berenergi 6 MV 10 MV. Pencocokan kurva regresi (linear fitting curve) digunakan penentuan linier. Hasil menunjukkan bahwa semakin besar uji maka liniernya meningkat. Nilai tertinggi dimiliki oleh material C5 yaitu 2,03 g/cm3. Material memiliki 0,0524 cm-1 HVL 13,23 cm 0,0419 16,54 energi Kata kunci: beton; HVL; linier; ABSTRACTRadiation shields with high linear attenuation coefficient values and economical prices are considered in the development of radiation shields. Materials that have potential to be developed iron sand pumice. In this research, we investigated effect variations composition sand-pumice aggregate mixture on density value as well concrete thickness its ability absorb x-ray radiation. Testing using photon beams energies Linear curve is used determining value. The results showed greater test concrete, higher highest owned by material, which 2.03 has 0.0524 other sample an 13.23 0.0419 16.54 respectively for energies. Keywords: concrete; coefficient; X-ray.
