What is alpha decay?

Alpha emitters have a place of their own when it comes to radiation protection. Learn more about the properties and effects of alpha radiation in the following article.

What is radioactivity?

Radioactivity surrounds us all, at any time in any place. Learn more about the physical phenomenon and how radioactivity is caused in this article.

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! 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,...
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.
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.
Choosing the best filter combination is very important to achieve the best performance in any fluorescence-based assay. Learn more about our recommendations.
As a rule of thumb, white microplates are used for luminescence and black ones are used for fluorescence, but there are many other plate types and assays.
In this article you will find the formula to convert from Irradiance (in W/m²) into quantum flux (in µE) when wavelength is expressed in nm.
