How do nuclear and chemical reactions differ? Which nuclear decay product is the slowest? How do beta particles and positrons differ? If polonium-210 is unstable because it has too much mass, what decay product is it most likely to produce to become stable? What is the definition of a half-life? What is the identity of the unknown product of beta decay of rhenium-187?^187_75 Re rightarrow^0_-1e+ What nuclear decay particle is created by the decay of potassium-40 to calcium-40? A 0.050 mg dose of iodine 131 was administered to a patient to treat hyperthyroidism. What is the remaining mass after 32.4 days? The half-life of iodine-131 is 8.1 days Isotopes are used in medicine for cancer treatment and medical imaging. Name an isotope for treatment as an example Now name another isotopes used i medical imaging, and the name of technique Why would isotopes used for cancer treatment not be used for medical imaging? Name three of the five principles for minimizing exposure to ionizing radiation Which measurement is most useful for detecting harm to personal from radioactive material, the roentgen or rem?

Explanation / Answer

Answer 1: Gamma radiation is a decay emission of pure energy. There is no other particle forms only energy in the form of gamma rays released.

Answer 2: Alpha rays or alpha particles are helium nucleus which contains two protons and two neutrons.It is heavy particle among other radioactive particle so it travel few distance. It has the least penetration power.

Answer 3: A beta particle, sometimes called beta ray, denoted by the lower-case Greek letter beta (). Two forms of beta decay, and +, respectively produce electrons and positrons are considered.

Symbol: decay (electron emission) and + decay (positron emission)

Answer 4:

Sl/No

NUCLEAR REACTION

CHEMICAL REACTION

Nuclear reaction takes place in the atom’s nucleus.

Electrons in the atom are responsible for chemical reactions.

Nuclear Structure of atomic species changes.

Nuclear Structure of atomic species remains unchanged. Only rearrangement of electrons happens.

Protons and neutrons react inside the nucleus.

Electrons react outside the nucleus.

It has a very high-energy change.

It involves only low energy change.
