A shielding rate of 34.6% with a 5 cm thick plate of cesium-137 (dose of 10 megabecquerels)! "Construction period and costs can be saved by about 30% compared to other methods."

The "JP Series" is a radiation shielding ceramic that has a higher shielding rate than concrete and can be applied in a thinner layer. It is a powdery ceramic primarily made from barium sulfate, combined with several types of binders to increase its specific gravity to around 4, thereby enhancing its density and improving radiation shielding effectiveness! When applied in open spaces, it can achieve a cost reduction of about one-tenth compared to decontamination work that involves excavating the ground. Additionally, it is effective in preventing cracks in containers! 【Features】 ■ Higher shielding rate than concrete ■ Can be applied thinner than concrete, allowing for shortened construction periods ■ Usable anywhere, simply by mixing with water ■ Cures quickly in just 3 hours, leading to faster construction times ■ Chemical resistance and weather resistance are excellent due to the ceramic material, with no degradation ■ Compressive strength is also stronger than that of concrete! *For more details, please refer to the PDF document or feel free to contact us.

basic information

By applying a thickness of about 3 to 5 centimeters to soil with a radiation level of approximately 4 to 5 microsieverts, a shielding rate of about 45% to 60% can be achieved! 【Other Features】 ■ Chemical and weather resistance is excellent due to the ceramic material, preventing deterioration. ■ Compressive strength is stronger than that of concrete. ■ Construction time and costs are reduced to one-third compared to other methods. ■ This method does not decontaminate the soil but instead contains the radiation to prevent it from being emitted. ■ By simply mixing rubber into the powder, a shielding rate greater than that of concrete can be achieved! *For more details, please refer to the catalog or feel free to contact us.
