[QUOTE="BLK03SVT10TH, post: 3373980, member: 13915"] Here is a little info about Radiation and some info from the Energy Departments Web Site about Dosage and the Radiation Signs and there meanings. I hope this helps keep you alive and able to father children. And now a little story about Radiation signs and people who don't think they mean anything. Back in the early 1980's I worked for a company in San Diego who was contracted to X-Ray all the Trolley Tracks for the San Diego Trolley (Basically a Chemical Weld Approx 6" Thick X 4" Wide in a Piece of Railroad Track) We had mobile X-Ray capability utilizing 100 Curies or Iridium192 (Very Radioactive Stuff) that was stored and transported in a 50 lb. Box made of Depleted Uranium 235 (Basically we were using crap that would kill you or make things start falling off your body if you got enough of it or touched it.) We would setup our X-Ray Exposures in Downtown San Diego in the middle of the day using all the Radiation Signs in the world along with Yellow Radiation Tape at the correct distances in order to control the area and keep people from being "Exposed" to any Radiation. It never failed that some idiot on the way to get some coffee or their lunch or just lazy would lift up the Radiation Tape / Rope and go right under and walk right over top of the shot or near enough to be dangerous. We would have to run in there and get their dumb asses out of danger. Anyway, don't treat those signs to lightly, they are posted for a reason. RADIATION - You can't see it, you can't smell it, and unless your really getting nuked, you can't taste it. So if you don't have Radiation Monitoring Equipment (The correct kind for the type of Radiation your Monitoring and in the right Scale/Range) and or Dosimeters to Monitor your exposure, I'd be VERY CAREFUL OUT THERE! A Short Lesson in Radiation Exposure (I'm a little rusty at this stuff so pardon me if I've made any errors) 1/2 the Distance = 4 X the Exposure All the Way Down to Point of Contact See how this Example of a Low Dose Source @ 24 Feet soon becomes POTENTIALLY DEADLY: @ 24 Feet Exposure = 2.5 millirems Per Hour (This is considered slightly above SAFE for most workers in jobs like X-Ray Technicians) @ 12 Feet Exposure = 10 millirems Per Hour @ 6 Feet Exposure = 40 millirems Per Hour @ 3 Feet Exposure = 160 millirems Per Hour @ 1.5 Feet Exposure = 640 millirems Per Hour @ 9 Inches Exposure = 1280 millirems or >1.2 rems Per Hour @ 4.5 Inches Exposure = 5120 millirems or >5 rems Per Hour @ 2.25 Inches Exposure = 20480 millirems or >20 rems Per Hour @ 1.125 Inches Exposure = 81920 millirems or >81 rems Per Hour THIS EXPOSURE X 8 HOURS AND YOU WOULD BE DEAD! (This is almost touching, but you can keep going down to point of contact.) These are some Tables from the Energy Departments Web Site Acute Radiation Exposure Effects of Large, Whole-Body Radiation Doses Effect Dose (rems) No observable effect 0-25 rems Slight blood changes 25-100 rems Significant reduction in blood platelets and white blood cells (temporary) 100-200 rems Severe blood damage, nausea, hair loss, hemorrhage, death in many cases 200-500 rems Death in less than two months for over 80% >600 rems Table 2-3 Criteria for Posting Radiation Areas AREA DOSE RATE CRITERIA POSTING Radiation > 0.005 rem/hr "CAUTION, RADIATION AREA" Area and < 0.1 rem/hr "Personnel Dosimeter Required at 30 cm. for Entry" High > 0.1 rem/hr at "DANGER, HIGH RADIATION AREA" Radiation 30 cm and < 500 "Personnel Dosimeter, Area rad/hr at 100 cm. Supplemental Dosimeter and RWP Required for Entry"* Very High > 500 rad/hr at "GRAVE DANGER, VERY HIGH Radiation 100 cm. RADIATION AREA" Area "SPECIAL CONTROLS REQUIRED FOR ENTRY"* Hot Spot 5 times general "CAUTION, HOT SPOT" area dose rate and > 0.1 rem/hr Table 4-1 Labeling Requirements for Radioactive Materials ITEM/MATERIAL REQUIRED LABELING Equipment, components and "CAUTION, RADIOACTIVE other items that are MATERIAL" radioactive, potentially radioactive or have been exposed to radioactive contamination or activation sources Sealed and unsealed "CAUTION, RADIOACTIVE radioactive sources or MATERIAL" or standard associated storage containers radiation symbol Equipment, components and "CAUTION, INTERNAL other items with actual or CONTAMINATION" or "CAUTION, potential internal POTENTIAL INTERNAL contamination CONTAMINATION" Components, equipment or other "CAUTION, FIXED CONTAMINATION" items with fixed contamination [/QUOTE]
