Lactose and sucrose aqueous solutions for high-dose dosimetry with 10-MeV electron beam irradiation

Abstract

In the present study, dosimetric characterisation of aqueous solutions of lactose and sucrose was analysed by UV spectrometry following irradiation using 10-MeV electron beam at doses between 0.5 and 10.5 kGy. As a dosimetric index, absorbance is selected at 256 and 264 nm for lactose and sucrose aqueous solutions, respectively. The intensity of absorbance for irradiated solutions depends on the pre-irradiation concentration of lactose and sucrose. The post-irradiation stability of both solutions was investigated at room temperature for a measurement period of 22 d.

“…At lower pH, double absorption spectra are seen at 402 and 520 nm which are attributed to the transverse and longitudinal plasmon bands indicating the formation of nanorods and some nanoparticles . From Figures and , the adsorption peak at 269 nm is attributed to lactose and with increasing pH the rod formation increases and only a single broad peak is seen. , …”

“…22 From Figures 1 and 2, the adsorption peak at 269 nm is attributed to lactose and with increasing pH the rod formation increases and only a single broad peak is seen. 23,24 At pH 8, with a constant temperature of 60 °C and an increasing time interval from 15 to 120 min, the spectrum gives a sharp peak at 420 nm because of the formation of fabricated non-agglomerated particles (Figure 3). The heating of colloids converts the shape of the silver nanorods to spheres.…”
