Are lab grown diamonds Radioactive?

No, lab-grown diamonds are not radioactive. Lab-grown diamonds, also known as synthetic or cultured diamonds, are created using various techniques such as chemical vapor deposition (CVD) and high-pressure high-temperature (HPHT) processes. These processes do not involve the use of radioactive materials, and the resulting diamonds do not become radioactive.

Radiation can be a concern in some contexts, such as natural diamonds that have been exposed to certain types of radiation, but this is not applicable to lab-grown diamonds. Lab-grown diamonds are composed of carbon atoms arranged in a crystal lattice structure, just like natural diamonds, and they do not possess any inherent radioactivity.
