What prices have you got listed? Is the equipment sensitive enough to get lots of entropy from a normal environment or do you need artificial sources of radioactivity? (easy, safe and cheap enough to get?)

The tag on my Montana Sunshine Radon Mine radon pillow is a little blurred. I think the following is the right phone number. Sunshine Mine is an amusing concept. People pay money to go breathe radon there, while others are spending much money avoiding radon. Anyway, the pillows make nice sources and good conversation pieces. bd

Safe, easy-to-obtain gamma sources: orange fiesta-ware pottery (at flea markets), old-style Coleman lantern mantles (not sure about the new ones), uranium-ore "health pillows" (Sunshine Mine, 408-225-3670). ^^^ 406
