US lab's new patch to protect cancer patients from harmful radiation

Researchers at Sandia National Laboratories in the United States have developed a novel, disposable patch designed to protect cancer patients and military personnel from harmful radiation exposure. This wearable dosimeter, created using advanced light-sensing polymers and microelectronic grids, can be worn on the skin or clothing and produced at scale. It provides real-time feedback on radiation delivery during therapy, enhancing treatment accuracy by tracking both the location and dosage of radiation as it passes through the patient. The patch can detect patient movement and instantly shut off the radiation beam to prevent damage to healthy tissue, addressing a significant challenge in radiation therapy, especially for children who are more vulnerable to adverse effects. The technology aims to improve situational awareness not only in medical settings but also for military personnel operating in hazardous environments, potentially enhancing long-term health outcomes and readiness. Motivated by personal experiences with cancer, the Sandia team continues to refine the patch to better protect patients, healthcare providers, first responders, and warfighters from toxic radiation exposure.
