The current honour of U of T carillonneur is held by Roy Lee, who says making the bells sing requires a careful touch. “I can feel the instrument, and it is reacting to my touch.” The massive musical instrument is kept inside the Soldier’s Tower at the university, up 95 steps.
Some listeners might assume that the bells are automatic, but Lee says a trained ear can tell the difference.
This process of ingesting C-14 continues as long as the plant or animal remains alive.
The C-14 within an organism is continually decaying into stable carbon isotopes, but since the organism is absorbing more C-14 during its life, the ratio of C-14 to C-12 remains about the same as the ratio in the atmosphere.
As the Earth's upper atmosphere is bombarded by cosmic radiation, atmospheric nitrogen is broken down into an unstable isotope of carbon - carbon 14 (C-14).
The unstable isotope is brought to Earth by atmospheric activity, such as storms, and becomes fixed in the biosphere.A symphony of bells rang out across the University of Toronto on Friday, celebrating graduation for 1,400 students and nine decades of musical tradition.The chorus of bells have played out at the downtown campus for the past 90 years.Because it reacts identically to C-12 and C-13, C-14 becomes attached to complex organic molecules through photosynthesis in plants and becomes part of their molecular makeup.Animals eating those plants in turn absorb Carbon-14 as well as the stable isotopes.For various reasons the project was not completed, and for about a year the apparatus stood idle for lack of financial support.
