Pengaruh Banyaknya Radiasi dan Perubahan Energi Sinar-X terhadap Peningkatan Pembentukan Radikal Bebas pada Air

Abstract

The method used in the research was quantitative that was experimenting on water (H₂O), which was subjected to x-ray radiation with tube voltage variation and calculating the level of peroxide (H₂O₂) in water that has been exposed to radiation. The study was conducted by irradiating one liter of water added with five milliliters of KMnO4 and one milliliter of H₂SO₄ as a catalyst with tube voltage variation of 40 kV, 60 kV and 80 kV with 200 mSec and 400 mA of 10 irradiation times. The analysis was performed using a spectrometer. The results find that the more radiation, the higher the free radicals are formed. While the higher the x-ray energy, the fewer free radicals are formed.
