The FBC Radioactive Sign is a medium-sized, hexagonal warning sign with a bold, black border and a vibrant yellow background. At its center is a stark black trefoil radiation symbol, surrounded by bold, uppercase black lettering that reads 'RADIOACTIVE'. The sign's surface is slightly weathered, with minor scratches and scuffs indicating its exposure to harsh conditions. The materials used are durable metal with a matte finish, ensuring visibility and longevity in the Federal Bureau of Control's surreal and often hazardous environments.
