“…Detektor ionisasi HP(10) standar sekunder sebagai instrumen untuk mengukur langsung besaran HP(10) mempunyai kelebihan lebih efisien, tidak memerlukan faktor konversi untuk mengkonversi ke besaran HP(10), dan tidak membutuhkan spektrometer untuk mengetahui distribusi spektrum foton (Ankerhold et al, 2001;Scarlat, Scarisoreanu, Badita, Mitru, & Vasilache, 2010). Detektor ini juga didukung oleh phantom PMMA yang telah teruji tingkat keseragaman berkasnya (Ankerhold & Ambrosi, 2010).…”

The value of Hp(10) can be measured directly using Hp(10) secondary standard chamber that developed by Physikalisch Technische Bundensalt (PTB), Germany. Hp(10) secondary standard chamber type T 34035/0046 is connected with electrometer PTW Unidos T 10001 / Ns.11814. In this paper, the exposure was carried out by X-ray sources and 137Cs for dose and radiation energy variations.The variations energy of X-ray were carried out using ISO 4037-1 quality narrow (N) spectrum within N-40 to N-300, while the radiation dose variations were carried out in the dose within range 0.1 mSv to 20 mSv. The use of the S-137Cs calibration factor for the Hp(10) secondary standard chamber with an X-ray irradiation source were carried out and obtained a fairly good response result not in all energy ranges. The result obtained a relatively constant response to energy of 65 keV to 250 keV (energy quality N-80 to N-250), this corresponds to the deviation obtained i.e ≤ 7% from the normalization reference source of 137Cs at 662 keV energy. Whereas for deviations below 3%, a relatively constant response has founded in the energy range of 100 keV to 250 keV (energy quality N-120 to N-250). The result obtained linier measurement on variations in dose according to changes in dose variation. The Hp(10) secondary standard chamber is capable for measuring variations of radiation dose, i.e from variations of 0.1 mSv to 20 mSv.
