“…Additionally, in a recent study by Luan and her colleagues (2013), 52 samples within 10 species of fish and 3 species of shellfish from markets in the Greater Vancouver Regional District were tested for the presence of radionuclides 134 Cs and 137 Cs. The study showed that none of the samples contained the radioactive cesium isotopes (Detection limit = 0.01 μSv/hr near the surface of the meter, corresponding to approximately 1 Bq) (Luan, Sidhu, & Zitouni, 2013).…”

Following the Fukushima Nuclear accident of March 11th of 2011, many people, particularly among the general public are still skeptical about the safety of foods imported from Japan. Furthermore, currently little radiation monitoring of food happens in Canada. The present study aims to test for the presence or absence of gamma radioactivity in various food products imported to Canada from Japan. Thirty commonly imported Japanese and thirty-two additional Canadian food products were purchased from supermarkets and convenience stores in Vancouver, British Columbia. All samples were tested for gamma radiation from cesium-134 and cesium-137 using a portable gamma spectrometer, the EXPLORANIUM GR-135 Plus Identifier. All food samples tested in this experiment were found free of any detectable gamma radioactivity.

“…Thus, it was concluded that the West Coast was minimally impacted by the contaminated waters due to the rapid dilution that occur in the Pacific Ocean. Furthermore if migratory fish were indeed exposed to this radioactive material, they were able to metabolize the radionuclides prior to reaching the West Coast (Luan, 2013). In addition to this research, a study conducted by Takeuchi et al analyzed the presence of radioactivity in food products imported from Japan.…”

Background and Purpose: The 2011 Fukushima Daiichi nuclear reactor incident in Japan resulted in the release of large quantities of radioactive material into the Pacific Ocean through deposition from the atmosphere and liquid discharges from the nuclear facility. Public misconceptions and the scarcity of radiation monitoring along the west coast of Canada have create doubt within the population regarding the safety of the ocean. A radiation survey along some of Vancouver’s beaches was completed to determine whether radioactivity from Fukushima has reached our local shores. Methods: Radiation surveys were conducted at three different locations; Sunset, Spanish Banks and Jericho Beach in Vancouver, British Columbia. Gamma radiation levels were measured using both the Radeye, GR 135 Plus EXPLORANIUM survey meters. At each beach, 30 samples of water, sand and various different artifacts including algae, stones and logs were each surveying. If the radiation detected exceed 0.05μSv/Hr the identification function of the GR 135 Plus EXPLORANIUM would be used to determine if it was from natural or artificial sources. The radiation levels were compared to the expected normal background levels (between 0.05μSv/Hr- 1.0 μSv/Hr) as well as to observed if there was any sufficient differences between the mediums under investigation. Results: The radiation levels along all three beaches did not exceed normal background levels (between 0.05μSv/Hr- 1.0 μSv/Hr). Furthermore, characteristic radionuclides released from this incident, specifically Cesium 134 and Cesium 134, were not detected. There was no sufficient difference between the radiation levels observed from the sand, water and different artifacts (logs, stones, and algae) Conclusion: It was concluded that the radiation levels along the beaches, Jericho, Spanish Banks and Sunset Beach do not present an additional risk to the public visiting this area as a result of this incident.
