Give the three types of radioactive decay occur in nature.

1.	Give the three types of radioactive decay occur in nature.
Answer» Three types of radioactive decay occur in nature : (i) α-decay in which a helium nucleus ⁴₂He is emitted; (ii) β-decay in which electrons or positrons (particles with the same mass as electrons, but with a charge exactly opposite to that of electron) are emitted; (iii) γ-decay in which high energy (hundreds of keV or more) photons are emitted. Each of these decay will be considered in subsequent sub-sections.

A bone containing `200 g` carbon-14 has `beta`-decay rate of `375` decay/min. Calculate the time that has elapsed since the death of the living one. Given the rate of decay for the living organism is equal to `15` decay per min per gram of carbon and half-life of carbon-14 is `5730 years`.A. 22920 yrB. 11460 yrC. 17190 yrD. None of these
Fusion processes, like combining two deuterons to form a He nucleus are impossible at ordinary temperatures and pressure. The reasons for this can be traced to the fact: (a) nuclear forces have short range. (b) nuclei are positively charged. (c) the original nuclei must be completely ionized before fusion can take place. (d) the original nuclei must first break up before combining with each other.
