In a present work an attempt was made to describe the radiochromic gels used in radiotherapeutic dosimetry to review the available solutions. Articles related to the composition and production of these gels were analyzed. Additionally, the application and properties of 3D dosimeters, such as radiochromic gels, were discussed. Cancer is one of the biggest problem of modern medicine and the reason to develop new and more accurate dosimeters. The gels discussed in this article allow to obtain promising results and confirm the validity of the continuation of research on both current and new solutions used in teleradiotherapy dosimetry.
