Radioisotopes

Suppose the mass of carbon in the bones of a dead organism is $500 \mathrm{g}$ and the activity is measured to be $30 \mathrm{atoms}/\mathrm{second}$. How old is the organism? Let the decay constant $\left(\lambda \right)$ of $\mathrm{C}‐14$ to be $3.83\times {10}^{-12} {\mathrm{s}}^{-1}$. 

Explain artificial radioactivity with examples.

Which of the following is a radioisotope?

Describe carbon dating.

An intense dose of radiation causes a lot of ionization in a cell, which can _____ the cell.

How does radiation affects a cell?

What is activity of a radioactive substance?

$1{\mathrm{C}}_{\mathrm{i}}=$$3.7\times {10}^{10} \mathrm{dps}$

One becquerel of radioactivity is equal to

STATEMENT-1: Specific activity of the same radioactive substance is same for 10g radioactive substance as well as 50g radioactive substance.

STATEMENT-2: Specific activity of a radioactive substance is its activity per g.
