Product Details
Completely safe for use in the science laboratory! Each source is mounted in a one-inch diameter sealed disc and is completely safe for student use. Three radioactive sources are available: Alpha, Beta and Gamma. Perfect for showing the different properties of all types of radiation. For instance, students will be able to see that alpha particles can be blocked very easily yet gamma rays are nearly impossible to block. The isotope name, type of radiation, activity in microcuries and half life are written on each sealed disc.
You may purchase three types of radioactive sources separately.
