IMPORTANT NOTICE - Your Privacy and Security Matters

Effective April 1, 2018, LANDAUER will transition to a paperless environment to protect our client's personally identifiable information (PII) for enhanced data privacy and information security purposes. LANDAUER will deliver all dosimetry reports electronically, via the secure portal. The practice of delivering dosimetry reports via U.S. Mail, Royal Mail (U.K.) and all other Courier Services such as FedEx, UPS, etc. will be discontinued.

More communication will be forthcoming over the next 2-3 weeks related to our transition to paperless. In the meantime, for more information, visit to review frequently asked questions, Live Chat with an Agent or contact a Customer Service Agent at 800-323-8830.
