X-ray composite fibrous color dosimeter based on 10,12-pentacosadiynoic acid

Abstract

Abstract An X-ray dosimeter is a device that detects and quantifies X-ray radiation. There is demand for a useful dosimeter with high sensitivity that works independently, has a low cost, and can be mass produced. In this study, a 10,12-pentacosadiynoic acid (PCDA)-based composite fibrous color dosimeter (CFCD) is developed for X-ray visualization and quantification on the order of a few grays (Gy). This CFCD is successfully prepared from PCDA and polylactic acid (PLA) using the centrifugal spinning (CS) method. The CFCD undergoes a color transition from white to deep blue with X-ray exposure in the range from 2.2 to 40 Gy. This color change is attributed to the polymerization process of PCDA. The prepared CFCD is a useful device for the detection and quantification of X-rays, exhibiting a maximum sensitivity of 2.2 Gy due to PCDA.
