PVC AS A POTENTIAL FILTER MATERIAL FOR IONISING RADIATION

Abstract

Introduction: Aluminum (Al) is a standard material that has been used as a filter for ionising radiation however for polyvinyl chloride (PVC) there is no solid evidence to support but has been recommended. PVC has been selected as a potential filter material due to it is a long lasting constructing material and very durable, which can be used in a variety of application. The purpose of this study was to observe the effect of PVC on entrance surface dose (ESD) values as compare to the standard X-ray filter of Al.

Method: The effect of varying thickness of the materials and difference exposure settings were observed and compared to each other.

Result: From this study, the percentage difference for both PVC and Al thickness is less than ± 25.00%.

Conclusion: The finding suggests that PVC has a potential to be used as one of the filter materials due to its ability to reduce the ESD value.
