While testing the rocks with a Geiger counter, they discovered one black rock—believed to be Allanite—registering a reading of 1500 (unit unspecified). The reporting party contacted Poison Control, who advised placing the rock in a cardboard box outside the property and seeking proper disposal. The reporting party is concerned about potential exposure and would like to safely dispose of the rock.
