Concept explainers
(a)
Interpretation:
The balanced nuclear reaction for the positron emission of Arsenic-74 has to be given.
Concept Introduction:
Positron emission reaction:
Positron particles are positrons (electrons with positive electric charge). Positron decay occurs when in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.
(b)
Interpretation:
The amount of samples remains after 90 days has to be given.
Concept Introduction:
Half-life:
The half-life of a radioactive substance is a measure of time taken for a given amount of the substance to reduce as an effect of decay.
(c)
Interpretation:
The volume of arsenic-74 administered has to be given.
