Medusa Maintenance & Support Membership

1. Introduction

Each Medusa sensor or software package comes with a Maintenance and Support membership which is free for the first year after delivery of your sensor.

The membership covers:

  • Access to maintenance and support on Medusa systems;
  • Use of and support with full stand-alone versions (including minor updates) of the following software programs;
  • Gamman (gamma-ray data processing);
  • MASS (windows-based data logger);
  • 4 hours of consultancy ("helpdesk") activities by Medusa Experts.  

After the first year, the membership can be extended on a yearly basis. This membership is intended to assure help and support beyond the standard terms and conditions provided with any Medusa system or software package. Please see below for a more detailed explanation of the membership.

2.  Contracting parties

The Medusa Maintenance and Support Membership is a contract between Medusa Radiometrics BV and an individual user of Medusa technology, or a company. In the latter case, client appoints a single contact person who covers the communication between client and Medusa.

3. Communication channels
