Detailed Description

Full assembled very unique microprocessor-controlled Radiation Illuminator Display is meant to be installed in a 8" x 10" x 1.2" thick shadow box (not included) and hung on a wall in your house. This large attractive display illuminates a unique universal radioactive symbol in the traditional red and yellow color as shown as cosmic rays strike it. In normal conditions, the center randomly lights up with cosmic rays, however, if you hold a vial of radium watch hands or other radioactive sources near its built-in SBM-20 Geiger tube the entire display glows brightly and fast "clicking" is heard (audio can be turned off). Includes AC adapter with 15 ft. cord. The unit includes a 9V snap to connect a 9V battery if your AC power goes out.
