NSP who could not confirm the question either way but did send us the following info provided by NSP’s Marketing Department. “Regarding the X-ray Radiation comment we talked about, we are unaware if UPS or the USPS Postal Service run the packages through an x-ray. We were able to find the following statement provided by our Marketing Department:
X-Ray Safety Statement
Exposing foods or dietary supplements to an x-ray machine at an airport or post office will not affect potency. An x-ray scan should not be confused with irradiation. If you took your herbs to the airport the amount of exposure in the airport is an extremely low dose from the x-ray scanners (0.15-0.17 millirads). The amount of radiation used for irradiation of foods is 1-10Kilograys (1gray=100rads) so that is a 100,000,000 times difference. There should be no effect on the herbs or health from brief exposure to x-ray scanners. Exposure to radiation from an x-ray machine is not considered comparable in any way to irradiation. Foods exposed to a common x-ray machine have not been shown to be altered in any way, unlike foods that are exposed to irradiation. NSP has strict quality control measures in place to ensure that none of the raw materials we receive are exposed to irradiation.”
Joy checked with both UPS and USPS. Packages being shipped via air are scanned in the same way as your luggage would be. If any suspicious item shows in the scan, the boxes are opened and hand checked and a notice is included when the package is re-closed stating that it was hand inspected. This scanning is not irradiation. It is the same low dosage your carry on items and luggage receive when going thru airline security checks.
