Artigo IPEN-doc 14347 Use of a standard ionization chamber at different distances in diagnostic radiology beams2009 - YOSHIZUMI, M.T.; AFONSO, L.C.; CALDAS, L.V.E.A secondary standard ionization chamber was calibrated, by a primary standard laboratory, at a determined distance. However, in the routine procedures of a calibration laboratory, sometimes the radiation detector cannot be positioned exactly at the calibration distance, for any reason. In this work, the response of a secondary standard ionization chamber was tested to verify the possibility of its use at different distances than at the calibration distance, using the same calibration factor.Artigo IPEN-doc 16720 Design and assembly of a simple monitor ionization chamber2010 - YOSHIZUMI, MAIRA T.; CALDAS, LINDA V.E.Artigo IPEN-doc 13363 Preliminary studies of a new monitor ionization chamber2008 - YOSHIZUMI, MAIRA T.; VIVOLO, VITOR; CALDAS, LINDA V.E.Artigo IPEN-doc 13362 Backscattered radiation into a transmission ionization chamber: measurement and Monte Carlo simulation2008 - YOSHIZUMI, MAIRA T.; YORIYAZ, HELIO; CALDAS, LINDA V.E.Artigo IPEN-doc 14770 Estudo comparativo da estabilidade de resposta de camaras de ionizacao monitoradas em feixes de radiacao X2009 - YOSHIZUMI, MAIRA T.; CALDAS, LINDA V.E.Artigo IPEN-doc 17634 Transfering calibration coefficients from secondary standard ionization chambers to transmission chambers2011 - YOSHIZUMI, MAIRA T.; CALDAS, LINDA V.E.Artigo IPEN-doc 17633 Performance of a ring-shaped monitor ionization chamber in standard radiotherapy beams2011 - GROPPO, D.P.; YOSHIZUMI, M.T.; CALDAS, L.V.E.Artigo IPEN-doc 14274 A new ring-shaped graphite monitor ionization chamber2010 - YOSHIZUMI, M.T.; CALDAS, L.V.E.Artigo IPEN-doc 14491 Preliminary studies of a new monitor ionization chamber2010 - YOSHIZUMI, MAIRA T.; VIVOLO, VITOR; CALDAS, LINDA V.E.Artigo IPEN-doc 15556 Backscattered radiation into a transmission ionization chamber: measurement and Monte Carlo simulation2010 - YOSHIZUMI, MAIRA T.; YORIYAZ, HELIO; CALDAS, LINDA V.E.
