THIS DAY IN SCIENCE: Penicillin Is Discovered - Sir Alexander Fleming in 1928

Select Page

I am concerned about the proposed inclusion of a lab investigation in the new SPH4U course involving the study of radioactive half life, using Cesium-137 as a source. Are there provincial regulations about the use of radioisotopes in high school science labs? If not, are there significant concerns for this activity to a degree that teachers should know about?
