An alpha particle (mass 6.6 x 10^-24 grams) emitted by radium travels at 3.4 x 10^7 plus or minus 0.1 x 10^7 mi/h. (a) What is its de Broglie wavelength (in meters)? (b) Whats uncertainty in its position? For part a I got -3.41 x 10^6 meters which said it. Other articles where Radium-226 is discussed: radium: Occurrence, properties, and uses: known; their half-lives, except for radium-226 (1,600 years) and radium-228 (5.75 years), are less than a few weeks. The long-lived radium-226 is found in nature as a result of its continuous formation from uranium-238 decay. Radium thus occurs in all uranium ores, but it is more widely distributed.
One gram of radium-226 undergoes 3.7 × 10 10 disintegrations per second, a level of activity that defined the curie (Ci), an early unit of radioactivity. This is an energy release equivalent to about 6.8 × 10 −3 calorie per second, sufficient to raise the temperature of a well-insulated 25-gram sample of water at the rate of 1 °C every hour.
