Lyoluminescence dosimetry with some saccharides

Area of Science:

• Radiation dosimetry
• Solid-state physics
• Biophysics

Background:

• Solid-state dosimetry offers advantages for radiation measurement.
• Lyoluminescence, light emission from irradiated solids dissolved in a solvent, is a promising phenomenon for dosimetry.
• Saccharides are biocompatible and readily available materials.

Purpose of the Study:

• To evaluate the lyoluminescent properties of mannose, glucose monohydrate, sucrose, and trehalose dihydrate.
• To assess their suitability as dosimetric materials in a novel solid-state dosimetry system.
• To investigate their response to X-rays, gamma-rays, and fast neutrons.

Main Methods:

• Lyoluminescence measurements were performed on aqueous solutions of selected saccharides.
• Irradiation was carried out using X-rays and gamma-rays.
• Dose measurements were made using a reader with an uncooled photomultiplier tube.
• Energy response to X-rays and response to fast neutrons were investigated.

Main Results:

• Saccharides exhibited measurable lyoluminescence, indicating potential as dosimetric materials.
• The system could measure radiation doses in the range of a few rad to approximately 100 krad.
• Experimental factors influencing dose measurements were analyzed, including X-ray energy response.
• Preliminary data on fast neutron response were obtained.

Conclusions:

• Mannose, glucose monohydrate, sucrose, and trehalose dihydrate show promise as lyoluminescent dosimetric materials for X- and gamma-ray detection.
• The developed dosimetry system is capable of measuring a wide range of radiation doses.
• Further research is warranted to fully characterize their response to various radiation types, including fast neutrons.
