Radisotopen (short name: RDTP ) is a chemical which was 100% mined off the planet of Roblox. In 2021, it was worth 3.484 quadrillion ROBUX per chunk, and very few Robloxians/companies own them. It is slightly radioactive, but is known for manipulating physics which is why it is so expensive to buy. The last person to sell their chunk of RDTP was in 1998. Robloxians on Kepblox found out their planet's oceanic crust was composed of 99% RDTP, 0.5% rock, and 0.5% granite. This led to an RDTP deflationary phase that lasted until 2025. By the time 2025 came, RDTP was only one ROBUX per chunk, which led to thousands of ships flying to Kepblox in an event known as the Kepblox Radio Rush. The Kepblox Radio Rush gradually turned to a peaceful company-wide conflict devoted to companies wanting more of RDTP. The peaceful company-wide conflict eventually started to gain violence, as physical fights of the companies began to be more common. There were even companies that were able to extract the radioactivity out of Radioisotopen and inject them to other weapons, gaining them radioactivity and using them to defeat companies. The Cirrus City Bank and native city banks were robbed by some companies because they were alleged to contain RDTP. Eventually, the conflict became interstellar, with Roblox and Kepblox fighting. However, in 2026, a volcano in Kepblox erupted and exploded, rendering 93% of RDTP on the planet to be heated and transformed to a normal crystal that was neither able to manipulate the laws of physics nor bend reality to one's will. Prices of RDTP went up approximately 14-15 times, which resulted in the price being 14-15 ROBUX per chunk, which caused the companies to immediately cease-fire, calling that all RDTP will be kept. After that, Kepblox gave the chemical a name in Barean, which is the language spoken on Kepblox. They named it كيببلوكسالنظائر المشعةسرعه.
