Question 1

Radiation is dangerous to organisms because
◦ it causes electrolysis of water in the cells.
◦ it ionizes molecules in the cells.
◦ it causes nuclear reactions in the cells.
◦ all radionuclides are poisonous.

Question 2

Carbon-14, which is present in all living tissue, radioactively decays via a first-order process. A one-gram sample of wood taken from a living tree gives a rate for carbon-14 decay of 13.6 counts per minute. If the half-life for carbon-14 is 5715 years, how old is a wood sample that gives a rate for carbon-14 decay of 3.9 counts per minute?
