Radioactive Isotopes

Radioactive Isotopes

Safe, affordable nuclear radiation sources for industry & hobbyists
Legal to buy & own with No License Required!
To ensure the longest half-life possible, all isotopes are fabricated to order and shipped directly to you from our NRC licensed nuclear isotope manufacturing facility in Oak Ridge, Tennessee.
Isotopes are never kept in stock - they are made to order.

Radioactive Isotopes CAN NOT be shipped outside the United States.
