Clues
- 14C forms in the upper atmosphere when 14N is bombarded by... (6, 4)
- A method of measurement: the counting of beta particle emissions over a standard length of time (12, 6)
- A type of dating: assigning a numerical age to an event (8, 6)
- A type of dating: deciding whether one event predates or postdates another event (8, 6)
- Calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e.g. 14C. A type of this dating method is radiocarbon (14C) dating. (11, 6)
- The exponential rate at which radioactive decay occurs as displayed on a graph (5, 5)
- The number of protons and neutrons in the nucleus of a carbon atom (4, 6)
- The process by which an unstable atomic nucleus loses energy by radiation and transform into stable isotopes, e.g. 14C -> 14N (11, 5)
- This technique allows the construction of year-by-year annual chronologies which can be temporally fixed (linked to the present day) or floating, e.g. dendrochronology (11, 6)
- Who won the Nobel prize for developing this technique in the 1940s? (7, 5)
