Studies of immigrants have provided unique opportunities for examining disparities in cancer screening and the impact of lifestyles and environmental exposures on cancer risk. Findings have been useful for planning cancer control strategies and generating etiological hypotheses. Although India is a leading source of immigration to British Columbia (BC), Canada, little is known about the cancer profiles of Indo-Canadians, information needed for planning health services and health promotion initiatives for this population. Using data from three population-based cancer registries, cancer incidence was compared for four population groups (in each of Delhi and Mumbai, India; Indo-Canadians in BC, Canada; and the BC general population) over three time periods (, and ). BC Indo-Canadians were identified by using Indian surnames. Age-standardized incidence rates (ASRs) for all cancers combined were lowest for men and women in Delhi and Mumbai, intermediate for BC Indo-Canadians, and highest for the BC general population. Ranking of common cancer sites and ASRs fo

Ernest Rutherford

The New Zealand physicist Ernest Rutherford, who lived from August 30, , to October 19, , was a trailblazer in the fields of nuclear and atomic physics. "The Father of Nuclear Physics" and "The greatest experimentalist since Michael Faraday" are two titles that have been applied to Rutherford. He was given the Nobel Prize in Chemistry in "for his investigations into the chemistry of radioactive substances and the disintegration of the elements." Along with being the first to do the winning work in Canada, he was the first Oceanian Nobel laureate.
Some of the discoveries made by Rutherford include the name and distinction between alpha and beta radiation, the notion of radioactive half-life, and the radioactive element radon. Rutherford and Thomas Royds are credited with establishing the helium nuclei's composition of alpha radiation. He postulated in that the charge of an atom is concentrated in its tiny nucleus. This was accomplished by his identification and explanation of Rutherford scattering following Hans Geiger and Ernest Marsden's gold foil experiment, which led to the development of the Rutherford model of the atom. He conducted experiments in in which he attacked nitrogen nuclei with alpha particles, resulting in the first artificia
