I think it is difficult to explain why other countries have set such low thresholds. However, as previously mentioned, we think that those thresholds are not scientifically justified. Moreover, as it was also mentioned, the limits in some cases apply to a single cellphone tower. They generally don't apply to all radiofrequency-emitting infrastructure. So it is really difficult to explain other countries' data, but we are confident that the thresholds established in Safety Code 6 are adequate.
