Problem

The steps below show three of the steps in the radioactive decay chain for 90232Th. The half-life of each isotope is shown below the symbol of the isotope.
Step (i) 232 90 Th (1.41 times 109 years) goes to 228 88 Rn (5.7 years). Step (ii) 228 88 Rn (5.7 years) goes to 228 89 Ac (6.1 minutes). Step (iii) 228 89 Ac (6.1 minutes) goes to 228 90 Th (1.9 years).

Identify the type of radioactive decay for the step (ii).
