Tibe2 rase rindu pada xrf..haha..rindu ke terpaksa rindu cos kene wat poster presentation..?? ngeh3..hehe, actually, my research abstract have been selected for poster presentation at the medical physics conference (final project during my master programme). so i hv to work harder, study all the xrf things..refresh all the things about indian mackerell..haha..it's a simple research, but i really enjoy doing the research..sgt2 best..atas tunjuk ajar dr. sabar n my fren yg dh kurus sekarang; suzanne, finally dpt gak hasilkan report yg ntah ape2 tu.. n sekarang i need to go through the report again..
after gone through the report for 3 days, haha, rasa mcm mengimbau kenangan lama ja..time 'bertungkus lumus' wat projek..time aku ngan suzanne tuang nitrogen utk detector, penuh asap (asap ke), wap kot kat atas lantai, rase cam tgh wat pementasan drama kayangan je,.haha..teringat zaman hari-hari naik moto ngan suzanne p beli ikan n udang kat market taman tun saadun..p beli sekoq, 2 ekoq, pakcik yg juai tu pun pelik..bila balik lab ja, en azmi beleteaq, bau hanyiaq ikan la, udang la dalam lab dia..haha..rase cam puas je tgk muke en azmi mase tu (sape suh die lambat order nitrogen)..kih3..
so nak kene refresh balik ape tu xrf..hehe..jOm2 kita same2 tgk betul ke tak...XRF adalah pancaran sinar-x sekunder daripada material/bahan yang teruja apabila dihentam dengan satu tenaga luar yang lebih tinggi (sinar-x @sinar-gamma) . apabila elektron dalam petala diganggu/diberi tenaga yang lebih, ia akan teruja ke aras tenaga yang lebih tinggi, then ia akan kembali ke aras tenaga yang asal, dan dalam masa yang sama ia akan memancarkan pancaran cahaya (sinar-x K, L M...), yang mempunyai tenaga yang spesifik merujuk kepada jenis material @ bahan yang digunakan..pancaran cahaya tersebut adalah XRF, sinar-x fluoresen..
kat bawah ni maksud sebenar yg saya dapat daripada buku Knoll..bace la ye, rase mcm same je.... (maksudnya x berkarat lagi otak aku ni..)
X-ray fluorescence (XRF) is the emission of characteristic "secondary" X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. When the orbital electrons in an atom are disrupted from their abnormal configuration by some excitation process, the atom may exist in an excited state for a short period of time. There is a natural tendency for the electrons to rearrange themselves to return the atom to its lowest energy or ground state. The energy liberated in the transition from the excited to the ground state takes the form of characteristic x-ray photon whose energy is given by the energy difference between initial and final state.
