About Us

Welcome to Radkut by Lango’s Design. Our parent company, Lango’s Design + Print has been in the paper and printing business since January 2000 where we’ve provided design, printing and paper products to customers worldwide. In June 2018, we were approached to manufacture numbered paper and foam smears for radioactive testing. Thus, RADKUT by Lango’s Design was born.  Our growth has been steady and we’ve sold thousands of paper and polyfoam smears to government agencies, universities and companies throughout the U.S. and internationally.

Our smears are used for testing your spaces for radioactive material. Check out this video from Iowa State's Radiation Department on Youtube: https://www.youtube.com/watch?v=sH77YrueOa0 and let Radkut work with you to keep your spaces rad-clean.
