Luminescence vs fluorescence and phosphorescence

We all think of something glowing when we hear the words luminescence, fluorescence or phosphorescence but the mechanism that stand behind these effects are somehow different. So, the question is, what sets them apart from each other?

Frequently Asked Questions

We have put together some commonly asked questions to give you more information on all our products, services and technologies.

If you however have a question you cannot find the answer to, please contact us !


Yes, all Berthold detectors are available with housings made of SS304 or SS316L which is essential to withstand the harsh environments radiometric devices are frequently exposed to. Especially for coastal or offshore applications housings made of 316L stainless steel are mandatory.
Yes, interface measurements are possible with radiometry. Not only is it possible to localize the interface layers between two phases, but also to measure a density profile for more complex processes. In this way, it is possible to visualize the heights of the different product layers inside the vessel and thus also monitor the properties of a transition phase, e.g. an emulsion. Learn more about…
Yes! The detectors SENSseries LB 480 from Berthold have been awarded SIL2 / SIL3 certification. This certificate covers the measurement applications level switch, continuous level and density.
Yes, but only if this is technically and, in your country, legally possible. At Berthold, we give our sources a recommended life-time of 15 years. After that we recommend to replace the source. Therefore, it is in the operator's responsibility to use the source longer. Radiation detection technology has improved over the years. In radiometric systems that have been in operation for a long time,…
No, because herein lies a significant advantage over conventional belt weigher systems. With a conventional belt scale, maintenance and servicing is extremely time-consuming. At regular intervals the operator's personnel must recalibrate the measurement and maintain the system, e.g. remove dirt and incrustations, lubricate moving parts, etc. This means not only personnel costs and time, it also…
Yes, but this can be easily compensated for with Berthold's Gas Property Compensation (GPC).
No! Berthold detectors have features (XIP or RID) that handle interfering radiation and thus maintain a stable and reliable measurement.
In principle, radiometric measurements are always safe, provided they are properly installed and it is ensured that the applicable regulations are complied with. Regular instruction of the personnel contributes significantly to a respectful and responsible handling. Since each measurement is designed customer-specific, only really necessary source activities and an optimum shield are used.…
Return of radioactive sources for all countries except Germany: Should you decide to return radioactive sources to us, international regulations for the transport, labelling and dose rate of radioactive materials must be observed and the regulations of the respective country. It is the full responsibility of the sender to fulfil and adhere to these regulations.
Please fill out this form if you want to send a measuring device to Berthold for repair. After you have submitted the form, you will receive a confirmation e-mail from us containing the RMA number. Please print this email and include it with the measuring device for shipment and keep the RMA number handy for any questions regarding this process.
