Radiochromic film containing poly (hexa-2, 4-diynylene adipate) as a radiation dosimeter
A radiation-sensitive polymer poly (hexa-2, 4-diynylene adipate)(PHDA) was synthesized
and incorporated into polyvinyl butyral films for radiation dose measurements in the 0.5–60
kGy range. PHDA undergoes crosslinking polymerization upon exposure to γ-rays, which
changes its color from very pale yellow to deep orange-yellow. The color change is directly
related to the absorbed dose. The absorption spectrum of the irradiated films features one
absorption band around 500 nm with a shoulder around 465 nm. With increasing absorbed …
