Nuclear medicine uses radiation to provide diagnostic information about the functioning of a person's specific organs, or to treat them. Diagnostic procedures using radioisotopes are now routine.
Radiotherapy can be used to treat some medical conditions, especially cancer, using radiation to weaken or destroy particular targeted cells.
Over 40 million nuclear medicine procedures are performed each year, and demand for radioisotopes is increasing at up to 5% annually.
Sterilization of medical equipment is also an important use of radioisotopes.

Answer: The value of 
is 2
Explanation:
Moles of 
= 1.0 mole
Volume of solution = 1.00 L
Initial concentration of = 
Equilibrium concentration of 
=
The given balanced equilibrium reaction is,
Initial conc. 1.0 M 0 M
At eqm. conc. (1.0-x) M (2x) M
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)
Given : 2x = 1.0
x= 0.5
Now put all the given values in this expression, we get :
Thus the value of is 2
Answer: Mendeleev's periodic law was that the properties of elements varies periodically with the atomic weight. Moseley's periodic law or modern periodic law is that the properties of elements are periodic function of their atomic number
