  2. 2. Key Data for the Reference and Relative Dosimetry of Radiotherapy and Diagnostic and Interventional Radiology Beams

    Författare :Hamza Benmakhlouf; Pedro Andreo; Klemens Zink; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Backscatter factors; Diagnostic radiology dosimetry; Mass energy-absorption coefficients; Monte Carlo; Output correction factors; Radiotherapy dosimetry; Reference dosimetry; Relative dosimetry; Small photon fields; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : Accurate dosimetry is a fundamental requirement for the safe and efficient use of radiation in medical applications. International Codes of Practice, such as IAEA TRS-398 (2000) for radiotherapy beams and IAEA TRS-457 (2007) for diagnostic radiology beams, provide the necessary formulation for reference and relative dosimetry and the data required for their implementation.

  4. 4. Micro-galvanic effects and corrosion inhibition of copper-zinc alloys

    Författare :Mattias Forslund; Jinshan Pan; Christofer Leygraf; Per Claesson; Jin Ying; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Copper; zinc; brass; octadecanethiol; IR Spectroscopy; AFM; atmospheric corrosion; aqueous corrosion; corrosion inhibition; Koppar; zink; mässing; oktadekantiol; IR-reflektions absorptionsspektroskopi; AFM; atmosfärisk korrosion; vattenaktig korrosion; korrosionsinhibering.; Chemical Engineering; Kemiteknik; Kemi; Chemistry;

    Sammanfattning :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. LÄS MER
