Chapter 42: Q 4 Conceptual question (page 1235)

Does each nuclear energy-level diagram in FIGURE Q42.4 represent a nuclear ground state, an excited nuclear state, or an impossible nucleus? Explain.

Short Answer

Expert verified

Therefore,

a.) Impossible.

b.) Impossible.

c.) Excited nuclear state.

Step by step solution

01

Given information

Nuclear energy level diagram in represented in the fig.

02

Explanation (a)

(a)In the 1n = state, only two neutrons are allowed. As a result, the answer is impossible.

03

Explanation (b)

(b)There must be one spin up and one spin down in each pair of protons and neutrons. As a result, the answer is impossible.

04

Explanation (c)

(c) A nuclear state in which one neutron has been excited to the 3n = level.

The plutonium isotope 239 Pu has a half-life of 24,000 years and decays by the emission of a 5.2 MeV alpha particle. Plutonium is not especially dangerous if handled because the activity is low and the alpha radiation doesn鈥檛 penetrate the skin. However, there are serious health concerns if even the tiniest particles of plutonium are inhaled and lodge deep in the lungs. This could happen following any kind of fire or explosion that disperses plutonium as dust. Let鈥檚 determine the level of danger.

What is the total energy (in MeV) released in the beta decay

of a neutron?

1.5 Gy of gamma radiation are directed into a 150 g tumour

during radiation therapy. How much energy does the tumour

absorb?

The uranium isotope U238is naturally present at low levels in many soils. One of the nuclei in the decay series of U238is the radon isotope R222n, which decays by emitting a localid="1650487447445" 5.50MeValpha particle with localid="1650487458663" t1/2=3.82days. Radon is a gas, and it tends to seep from soil into basements. The Environmental Protection Agency recommends that homeowners take steps to remove radon, by pumping in fresh air, if the radon activity exceeds 4pCiperliterof air.

a. How many R222natoms are there in 1m3of air if the activity is 4pCiL?

b. The range of alpha particles in air is 鈮�3cm. Suppose we model a person as a 180-cm-tall, 25-cm-diameter cylinder with a mass of 65kg. Only decays within 3cmof the cylinder can cause exposure, and only 鈮�50%, of the decays direct the alpha particle toward the person. Determine the dose in mSvperyearfor a person who spends the entire year in a room where the activity is 4pCi/L.

c. Does the EPA recommendation seem appropriate? Why?
