摘要：

Spatial and temporal variations in the atmospheric bomb radiocarbon make it a very useful tracer and a dating tool. With the introduction of more atmospheric bomb radiocarbon records, the spatial and temporal changes in bomb radiocarbon are becoming clearer. Bomb radiocarbon record from a pine tree in the northern Israel region shows that the Delta 14C level in the region is closer to the northern hemisphere zone (NH) 1 as compared to the northern hemisphere zone (NH) 2. A comparison of this pine's Delta 14C record with a nearby olive tree's Delta 14C values also highlights changes in the growing season of the olive wood from one year to the other. The observation suggests that olive wood 14C ages can show offset compared to the IntCal curve, and thus they should be interpreted cautiously.
