【 摘 要 】

Emulsified diacetylenes as reporter molecules in micelle gel dosimeters were evaluated in the current article. It was observed that gels containing PCDA emulsified in deionized water using SDS changed from colourless to blue upon irradiation. Unfortunately, recipes that led to turbid gels resulted in a colour change, but transparent gels did not change colour. The colour change may be due to the oligomerization of precipitated solid PCA crystals, rather than emulsified PCDA.
