This study presents a flowchart to identify radioisotope (RI) contamination in X-ray receptors and a wipe test method for effective decontamination, successfully removing RIs from imaging plates.
Area of Science:
- Medical Imaging Physics
- Radiological Protection
- Nuclear Medicine Technology
Context:
- Hospitals are encountering black spots in medical images, indicative of radioisotope (RI) contamination.
- X-ray receptors, including imaging plates (IPs) and cassettes, are susceptible to contamination.
- Accurate identification and removal of RIs are crucial for maintaining image quality and patient safety.
Purpose:
- To develop a systematic flowchart for diagnosing RI contamination in X-ray receptors.
- To propose and validate an effective chemical wipe test method for removing adhered RIs.
- To address the issue of black spots in medical images caused by radioactive contamination.
Summary:
- A diagnostic flowchart assesses RI activity levels and contamination on surfaces and within parts of X-ray receptors.
- A wet chemical wiper wipe test method was employed for decontamination.
- The procedure successfully identified contamination sources and removed RIs from an imaging plate in a clinical setting.
Impact:
- Provides a clear protocol for hospitals to manage and resolve RI contamination issues in imaging equipment.
- Demonstrates the efficacy of a practical decontamination method, improving the reliability of medical imaging.
- Contributes to enhanced radiation safety protocols within healthcare facilities.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
