WebHá 2 dias · X-ray and Gamma Radiation Shielding Materials. In most cases, high-density materials are more effective than low-density alternatives for blocking or reducing the intensity of radiation. However, low-density materials can compensate for the disparity with increased thickness, which is as significant as density in shielding applications.
