A β-emitting radiation source gives 250 units of radiation at a distance of 4.0 m. At what distance does the radiation drop to one-tenth its original value?

Bone and bony structures contain calcium and phosphorus.a. Why would the radioisotopes calcium-47 and phosphorus-32 be used in the diagnosis and treatment ofbone diseases?

How can a nucleus emit an electron during β decay when there are no electrons present in the nucleus to begin with?

In problems5.51 to 5.54, a nucleus is shown with protons and neutrons.

Draw the nucleus that emits a beta particle to complete the following: (5.2)

The red arrow in the graph (see margin) indicates the changes that occur in the nucleus of an atom during a nuclear reaction. Identify the isotopes involved as product and reactant, and name the type of decay process.

Complete each of the following nuclear equations and describe the type of radiation:c. ⁶⁶₂₉Cu → ⁶⁶₃₀Zn + ?
