NTP produces, processes and supplies bulk radioactive sealed sources and designs and manufactures source containers for the transport of radioactive materials.

NTP Radioisotopes and NTP Europe manufacture and process and, together with Gammatec NDT Supplies, market and distribute high-quality radioactive sources, equipment and containers used in industrial radiography markets.

Radioisotope-based sources are used for non-destructive testing (NDT), process control measurements, and have many applications including:

Level and density control
Flow rate measurement
Belt weighing
Static elimination
Column scanning
Moisture measurement

Radioactive sources manufactured by NTP group include iridium-192, used extensively for the non-destructive testing of welds, process vessel walls and piping; cobalt-60; and caesium-137, used in process control applications.
