Abstract: Lead is one of the most common elements used in radiation protection but has been associated with adverse effects on health and toxicity. In this study, a lead-free thyroid protector was elaborated for patients undergoing diagnostic imaging to protect them from X radiation and its stochastic effects. Physical, chemical, and structural properties were studied using characterization techniques. Mechanical tests such as resistance and elongation to traction, bending, and impact were performed, and thermogravimetric analysis (TGA) was used to establish the safe temperature for which the material is invariant. The attenuation test against X-rays was carried out in a PANalytical X'pert PRO equipment, in the transmittance function. Finally, experimental measurements were made in a mammography service using OSL detectors to evaluate the material's efficacy in a real scenario. An attenuation of the incident X-radiation intensity of about 90% for the thyroid was obtained (29 kV). These results confirm the viability of the lead-free protectors developed against ionizing radiation in radiological protection.
