Lithium lactate as an ESR dosimeter

Radical formation in lithium trifluoromethane-sulfonate for ESR dosimetry

“…The requirement of tissue-equivalent dosimeter leads us to use Li and Mg compounds rather than to use heavy alkali or alkali earth ions for metallic cations. Li and Mg-lactates meet well the dosimetrical and practical requirements, as they are much more sensitive to radiation than alanine [7][8][9].…”

“…Dosimetric applications of ESR have been successfully made for intermediate-and high-dose ranges with alanine as a dosimetric material [1][2][3]. Efforts to use ESR dosimeter in health physics have resulted in a minimum detectable dose of 10 mGy for sugar and 100 mGy for Li and Mg-lactate [4][5][6][7][8][9].…”

“…A series of organic ionic compounds have been recently developed as a hybrid of metal ions and organic materials [7][8][9]. The requirement of tissue-equivalent dosimeter leads us to use Li and Mg compounds rather than to use heavy alkali or alkali earth ions for metallic cations.…”

The Effect of Gadolinium on the ESR Response of Alanine and Ammonium Tartrate Exposed to Thermal Neutrons

“…The ESR technique has become an international standard for dose measurements through alanine (13). However, in the last decade various new materials have undergone detailed analyses and studies designed to improve the effectiveness of ESR in radiation detection, including various organic and inorganic compounds such as ammonium tartrate (14,15), lithium lactate (16), magnesium lactate (17), and formates and dithionates (18). These compounds show good sensitivity for photon and electron beams, but the response for thermal neutrons is very inadequate.…”

Study on the EPR/dosimetric properties of some substituted alanines

“…These studies, aimed at increasing the sensitivity of SS/EPR dosimetry at low doses, are focussed mainly on the two features above, materials with higher or comparable ''radiation chemical yield'' and with narrower or simpler EPR spectra than those of alanine. Recently, very promising studies on lactates (Hassan and Ikeya, 1997;Hassan et al, 1998), alkaline-earth dithionates (Bogoushevich et al, 1996;Bogoushevich and Ugolev, 2000;Lund et al, 2002), ammonium tartrate (Olsson et al, 1999(Olsson et al, , 2000Yordanov and Gancheva, 2004) and formates Vestad et al, 2003) have been published.…”
