The half-life of radium is about 1600 years. Of 100 g of radium existing now, 25 g will remain unchanged after:
- A
2400 years
- B
3200 years
- C
6400 years
- D
4800 years
Two half lives later, 100g of gamma rays will be reduced to 25g.
100/2² = 25
The half life of Radium = 1600 years
Time taken = 2×1600
= 3200 years
Two half lives later, 100g of gamma rays will be reduced to 25g.
100/22 = 25 The half life of Radium 1600 years
Time taken = 2x1600 = 3200 years
Two half lives later, 100g of gamma rays will be reduced to 25g.
100/22 = 25 The half life of Radium 1600 years
Time taken = 2x1600 = 3200 years
Two half lives later, 100g of gamma rays will be reduced to 25g.
100/22 = 25 The half life of Radium 1600 years
Time taken = 2x1600 = 3200 years
Two half lives later, 100g of gamma rays will be reduced to 25g.
100/22 = 25 The half life of Radium 1600 years
Time taken = 2x1600 = 3200 years
