PHOTONICS APPLIED TO IONIZING RADIATION
Exploring New Radiation-Resilient Materials
Several radiation dosimeters based on electronic chips are highly reliable. However, photonic sensors can be more radiation-resilient than traditional electronic chips making the latter more suitable to operate in harsh environments.
The defense sector of countries with extensive borders, such as Brazil and the USA, can enormously benefit from this type of ionizing radiation detector once they could be easily transported and adapted into different spatial configurations. Moreover, an ionizing radiation photonic sensor could give near real-time reading, meaning that any nation provided with this type of sensor will detect radiological threats on the fly.
Also, Goiânia is known for its medical centers that attend most cities of the Brazilian Midwest, including radiological treatments. In this context, biocompatible photonic materials with the ability to respond to low doses of radiation integrated into photonic devices can measure the real dose absorbed by the human body, for example, during an interventional surgery.
This line of research aims to incorporate radiation-sensitive and resilient materials into photonic devices to create a novel dosimeter with a wide-range working operation.
