We are pleased to announce that Theta-Consult Ltd. is now the official representative for Bulgaria of Radonova Laboratories AB, a Swedish company and global leader in radon measurement.

Why is this important?

Radon is a naturally occurring radioactive gas that is the leading cause of lung cancer after smoking. Its accurate measurement is crucial to ensuring a healthy environment in homes, offices, and public buildings. The measurement and control of radon concentration in Bulgaria are mandatory and regulated by the Law on the Safe Use of Nuclear Energy (LSUNE), the Ordinance on Radiation Protection (ORP), and Ordinance No. RD-02-20-1 of April 3, 2019, on the technical requirements for buildings for protection against radon.

What does the partnership mean for our customers?

This strategic partnership significantly expands Theta-Consult’s portfolio in the field of radiation control and enables Bulgarian customers to gain direct access to high-quality, reliable, and, last but not least, accredited radon monitoring services.

The guests also had the word, some recounted memories, others read congratulatory addresses, others thanked for the sponsorship.

And so, in cheers and talks, memories and smiles, the celebration turned into an exciting experience for both us and our guests.

And finally, as for every birthday, there was a big cake, with a special decoration made by our colleague Addy Boyadzhieva.

This is a picture of the whole Theta team around the cake with big smiles and 30-years anniversary pins, as a memory of the celebration!

Our celebration ended with a piece of cake and wine.

Hooray, we already have a SUSI Certificate! From 2019 Theta Consult Ltd. is working on the priority goal Development, implementation and Certification of Information Security Management System (ISMS), but for various reasons, this still did not happen.

From the beginning of 2020, at the insistence of the top management, more decisive steps were taken and with the help of a consulting company and the mobilization of its own staff, things worked out.

The new system includes both the general characteristics (processes) of a Management System (MS) and very specific requirements (controls) for Information Security (IS), and thus the whole ISMS system is formed.

A team of three specialists (Responsible for the three systems: ISMS, OHSAS and QMS) works under pressure (due to the short deadlines), but responsibly and selflessly. So, the collective mind and efforts gave the desired result!

At the end of March, a certification organization conducted an audit (remote) and Theta Consult received a good assessment of what was done, and in early May received the desired Certificate of Conformity of SUSI with the requirements of BDS EN ISO / IEC 27001: 2017 .

Congratulations on your success! Congratulations to the company and staff!

Moisture content measurement system LB 350, manufactured by Berthold, is mainly used in applications where conventional sensor technologies are not applicable because of the conductivity or the chemical properties of the material being measured. “For continuous humidity measurement of solids, the LB 350 uses the neutron deceleration method. It uses the effect of neutron scattering as a result of the interaction of high-energy (fast) neutrons with the nuclei of hydrogen atoms in the material being measured”, the Process control department explained.

The measurement system is based on a source emitting a cloud of fast neutrons. After their interaction with the water molecules in the material being measured, the decelerated neutrons are measured with a special detector that is sensitive to only slow neutrons. Since the number of slow neutrons corresponds to the hydrogen content, the neutron technology is a reliable technical solution for measuring the moisture content of a product.

 “Neutron technology does not depend on the chemical or physical bonds between the water molecules in the measured volume”, commented Mariela Mladenova, a specialist in the field. “It is not affected by temperature, pressure, conductivity, color, pH value, electrolyte content or different particle sizes. Through it, even the content of deep-frozen water can be accurately estimated” the company experts added.

Measurement through the LB 350 system is accomplished by installing a bunker probe inside the tank or a surface probe against the wall of the vessel with the product being measured, depending on the specifics of the application.

SURFACE PROBE

The surface probe is mounted directly on the outer wall of a bunker. It is capable to irradiate up to 20 mm thick steel walls. However, the best measuring accuracy is achieved by using Berthold’s specifically designed mounting frame, which is installed in an opening in the wall. The mounting frame is extremely robust due to the wear-resistant ceramics surface and allows for a quick and easy installation of the probe.

BUNKER PROBE

The probe is mounted in a dip pipe made from steel or ceramics. Typically, this dip pipe is inserted in the outlet section of the bunker, so that the probe is fully surrounded by bulk material. Due to the optimum position of the probe inside the material flow, a highly representative measurement is achieved.

The LB350 system has proven it’s reliability and extremely accurate operation in multiple hard applications, including moisture measurement of sand int concrete or glass industry, as well as humidity determination of coke and sinter mixtures.

On November 28^th and 29^th, representatives of EA BAS (Bulgarian Accreditation Service) did Routine supervision and Extension of the accreditation range of Theta Consult’s Type C radiation control body

There are 2 new control parameters:

• Dose from Gamma, X-ray and neutron rays (important parameter in case of radiation control medical facilities, which diagnose and perform treatments of various diseases)

• Activity of Gamma radionuclides in various materials (important parameter for better analysis of samples from various controlled objects, mainly industrial)

The extension of the range was provoked by the market search. We hope, that this way we will meet the needs of more customers.

In the end of March 2020 the radiation control body, received it’s new certificate by BAS and is currently expecting it’s new customers.

More information about the Radiation control body you can find here, for some additional questions, please don’t hesitate to contact us!
