The radioisotope that has the longest half-life is the best to use in powering planet and space exploration vehicles because they can travel farther. Which radioisotope is the best to use?

The radioisotope that has the longest halflife is the best to use in powering planet and space exploration vehicles because they can travel farther Which radioi class=

Respuesta :

Answer:

U-238

Explanation:

For a given radioisotope, half life can be defined as the time taken for the isotope to decay into one-half of its original amount. Mathematically, this is expressed as:

[tex]t_{1/2} = \frac{0.693}{k}[/tex]

where k = rate constant for the radioactive decay process

Greater the t1/2 longer will be its stability.

Based on the given data, U-238 has the largest half life and therefore will be best suited for applications mentioned.

Answer:

Uranium-238 is the radioisotope which is best to use.

Explanation:

Half-life : The time in which the concentration of a reactant is reduced to half of its original value is called half life period.

As it has been given that radioisotope that has the longest half-life is best to use as power source planet and space exploration vehicles:

Uranium 238 is with the highest value of half life which is equal to [tex]4.5\times 10^9 [/tex] years.
