| 11. | Radium, being a decay product of uranium, is found in all uranium-bearing ores.
|
| 12. | The ratio is less than 190 when the decay products of each are included.
|
| 13. | Purified comes into equilibrium with its decay products after about a half of year.
|
| 14. | The gold did contain radioactive decay products of 222 Rn.
|
| 15. | Analysis of argon radioactive decay products yielded an age of 65.17 ?0.64 million years.
|
| 16. | Thus, in rapakivi zones, the hazard from radon, a decay product of uranium, is elevated.
|
| 17. | Uranium workers are routinely exposed to low levels of radon decay products and gamma radiation.
|
| 18. | Their decay products ('daughter'products ) are called radiogenic nuclides.
|
| 19. | Radon and its first decay products being very short-lived, the seed is left in place.
|
| 20. | Hassium has been observed as decay products of darmstadtium.
