RAS-ONE is Rasgo’s proprietary brand of lead-free radiation shielding materials. It is a single-layered shielding sheet that is uniformly mixed and dispersed with a high-purity, ultra-fine metal powder with excellent radiation shielding properties and a base resin with excellent chemical bonding. Also, a single layer of material has a solid shielding effect. With a special manufacturing method, it is thin and light and has excellent elasticity. Also, because it contains no lead, it is environmentally friendly and has excellent durability without crack. From X-Ray scanners used in airport security and food, to radiation protection suits in nuclear power plants, defense, industrial and medical sectors, RAS-ONE is designed to suit customer requirements for use in a variety of areas. RAS-ONE has passed tests by authorized institutions such as IEC61331-1 and ASTM F3094-14.
