The application of EPR dosimetry for radiotherapy and radiation protection

LET effects following neutron irradiation of lithium formate EPR dosimeters

“…Alanine has been used for dosimetry of radiotherapy beams like high energy electrons and photons (Chu et al 1989, Ciesielski et al 2003, Helt-Hansen et al 2009, Kudynski et al 1993, Mehta & Girzikowsky 2000, Onori et al 2006, and the dosimeter signal has also been studied after irradiation with other beam qualities (Hansen & Olsen 1986, Hansen et al 1987, Olko 2002. Regarding radiation absorption characteristics, alanine has properties quite similar to tissue or water, and thus shows a low energy dependence for high energy electron and photon beams , Bergstrand et al 2005, Bergstrand et al 2003, Zeng et al 2004, Zeng et al 2005.…”

Alanine/EPR dosimetry applied to the verification of a total body irradiation protocol and treatment planning dose calculation using a humanoid phantom

“…Most authors describing alanine measurements establish a dose response curve prior to dose calculation. [28][29][30][31] In this work, absorbed dose was determined using a 20 Gy base function S ala,b . The relative standard uncertainty on the dosenormalized amplitude of u͑Ā D ͒ = 25 mGy is close to the value of 20 mGy adopted at PTB.…”

Response of l-alanine and 2-methylalanine minidosimeters for K-Band (24GHz) EPR dosimetry

“…Nowadays, alanine/EPR dosimetry technique is broadly accepted for dosimetry of high radiation doses such as those used for radiation processing applications [21][22][23]. A plethora of work already also exists in the literature reporting the application of alanine/EPR dosimetry in radiotherapy [24][25][26][27]. All this work were done at the X-Band (9.5 GHz) as initially suggested initially by Bradshaw et al [28] and later by Regulla and Deffner [6].…”
