 Radioactive Bug 001 
Current GOAL: Travel between Geocaches. About this item: Radioactive Bug 001. Uranium Doped Marble. More commonly known as "vaseline glass", these marbles have been doped with around 3% uranium dioxide to give them a slight yellowish color and a beautiful flourescence under longwave ultraviolet light. A single marble emits very low gamma and beta radiation, so they are perfectly safe to handle. 07-Jun-2007 - I placed Radioactive Bug 001 (Travel Bug Dog Tag) in kit sobrevivencia-peninha Radioactive Bug 002 
Current GOAL: To travel around the world and visit Nuclear Plants. About this item: Radioactive Bug 002. RADIOLOGICAL DOSIMETER CD V-742. For more than a quarter of a century, Dosimeter has been a leader in the development, manufacture and distribution of radiation detection equipment. THIS IS A PERSONAL UNIT made to carry in your pocket to determine when maximum exposure has been reached. A radiation dosimeter is a pen-like device that measures the cumulative dose of radiation received by the device. It is usually clipped to one's clothing to measure one's actual exposure to radiation. Magnifying lenses (a low-power microscope) and an illumination lens allow one to directly read the dose by aiming the illumination lens at a light source and looking into the device. For personal use, this is the most useful device to measure radiation, because biological damage from radiation is cumulative. 07-Jun-2007 - I placed Radioactive Bug 002 (Travel Bug Dog Tag) in IMC No. 2 P-PT - Feel The Wind [Sintra] Radioactive Bug 003 
Current GOAL: To travel around the world and visit Dark Places. About this item: Radioactive Bug 003. NITE TRITIUM GADGET KEYRING GLOWRING GLOW STICK. If you have never seen these before, then get ready for something a bit different. The Nite GlowRing is the ultimate glow-in-the-dark keyring and the last word in ‘must have’ gadgets for the outdoor enthusiast. This self illuminating safety device has been originally designed for marking equipment and personal property that may need to be found in the event of an emergency during the hours of darkness. Made from durable polycarbonate available in three vibrant colours, the GlowRing will glow for over 10 years and is the ultimate accessory for Geocachers. Can be sumerged underwater up to a depth of 30m. Glowrings are laser sealed borosilicate glass vials which are internally coated with phosphor injected with gaseous tritium (this is the radioactive stuff) which reacts with the phosphor to create a cold energy which produces a low level light source with no filaments or heat dissipation and no risk of fire or explosion. They are unaffected by water, oil and most corrosive materials and require no external power source or exposure to light, remaining fail-safe and maintenance free with a lifetime in excess of 10-20 years. This item contains Radioactive H3 substance (a minute amount of phosphorous tritium contained in a unbreakable polycarbonate casing) but is perfectly harmless and in no way a danger to anyone! 13-Jun-2007 - I placed Radioactive Bug 003 (Travel Bug Dog Tag) in Praia do Cavalo [Sintra] Radioactive Bug 004 
Current GOAL: To travel around the world and visit Cool Places. About this item: Radioactive Bug 004. Radioactive Sign Fridge Magnet Radiation as used in physics, is energy in the form of waves or moving subatomic particles. (Quantum mechanics predicts that waves can exhibit particle behavior (photons for example) and particles can exhibit wave behavior (De Broglie Wave for example), this is commonly called Wave-particle duality). Radiation can be ionizing or non-ionizing radiation, depending on its effect on atomic matter. The most common use of the word "radiation" refers to ionizing radiation. Ionizing radiation has enough energy to ionize atoms or molecules while non-ionizing radiation does not. Radioactive material is a physical material that emits ionizing radiation.
