Radiation Test Reports Available - Guest Post by AIYA America

Monday, October 26th 2015 @ 1:30 PM

It is hard to believe that it has been over four years since the triple disaster struck off the coast of North Eastern Japan. Life in the affected areas is mostly normal now, but the impact of such a catastrophic event will never be forgotten. 

In their continuing efforts to keep their citizens safe from the potential dangers of radiation exposure, the Japanese government had announced back in April of 2012 that it would tighten its radiation exposure guidelines. The guidelines were specifically referring to the total concentration of CS-131, CS-134, and CS 137 –the three radioactive isotopes found in Eastern Japan in the wake of the nuclear disaster at Fukushima – with the maximum allowable amount being cut by 80%. Per the stricter guidelines, the allowable limit was cut from 500bq/kg to just 100bq/kg, thus making Japanese regulations for radiation the strictest in the world. (For reference, the United States have a listed maximum at 1,200 bq/kg, while the EU guidelines allow only 1000 bq/kg.)

Here at Aiya, we understand that radiation is a critical concern among many who are enjoying teas and products from Japan, and we are committed to the safety of our customers. That is why we have been conducting monthly radiation tests on our Matcha and loose leaf teas through an independent third party lab since 2011. By using an independent lab in the US, we believe we have been able to remain rigorously devoted to both safety and quality, while also ensuring a transparency in our testing that instills our customers with confidence and trust in the product. The results of these tests have continuously confirmed that our Matcha and green teas are safe to drink under all international regulations. For the added comfort of our customers, copies of our reports are always available upon request.

It is not uncommon for large tea manufacturers to conduct similar radiation tests, and to provide copies of their reports as well. As manufacturers, the safety of our customers remains our primary concern, and we believe that most other manufacturers feel the same way. It is our hope that this dedication to safety and transparency continue to set a precedent for all other manufacturers to follow within the tea industry.


EDITOR'S NOTE: Thanks to AIYA for addressing this ongoing question and concern by consumers. We appreciate Aiya's willingness to share some insight and information about the safety of tea.
