Product Description
Luminous Marker Disc with Pouch
Original WWII-era paratrooper luminous marker disc with accompanying pouch. These marker discs were issued for low-light identification and signaling purposes and feature original radium-based luminous paint (Radium-226), typical of U.S. military equipment manufactured during World War II.
807,000 average CPM with the Radiacode 102 documented in last picture
Still weakly self-luminous when observed in darkness after allowing vision to adapt
Please note: The internal radioluminescent matrix is cracked but still sealed inside the disc.
Point-source measurements with the Radiacode 102 were over 40 mR/h (gamma only) on contact. To comply with regulatory requirements — including the 0.5 mR/h package surface limit (beta + gamma) — the marker disc will ship wrapped in a 1/64" thick lead sheet in the center of a twelve-inch box!
Disclaimer: Although a point-source measurement for this specimen was over 40 mR/h, handling this specimen will not result in that dose rate to the entire body. This measurement is provided to illustrate the challenges of shipping the specimen and does not represent actual handling exposure, as the inverse square law states that radiation intensity decreases rapidly with the square of the distance from the source. As radiophiles, we can all do our part to stop the proliferation of radiophobia by sharing device-specific count rates for point-source measurements instead of unrealistic total-body dose rates.
Coin and devices not included.
