Frequently asked Questions

After the irradiation process, BGS checks by means of the dosimeters affixed to the product that the correct dose has been applied. After this, the products are ready for use without any waiting time.

The radiation used by BGS acts through the packaging. There is great flexibility of packaging types and materials, ranging from boxes, bags, pouches up to whole pallets. The decision for the optimal packaging is of great importance to achieve a homogenous application of the dose and good process efficiency. Key considerations in this regard include the density in the packaging and the number of units/pieces per packaging. Since BGS uses automated systems for the processing of your products, this provides the preferred option for cost reasons. Our specialists will be happy to advise you about the possibilities.

Depending on the radiation dose applied, there is no significant heat-up of the products during radiation. At higher doses that are normally required for crosslinking, a slight temperature increase will occur.

The energy of the rays is expressed in millions of electron volts, which describes the strength of the electrical field to accelerate the electrons. It is directly correlated to the penetration capability of the rays. It is limited to a maximum of 10 MeV through the design of our plants to avoid activation of products. The dose (or amount) of radiation is expressed by the unit Gray (Gy), which depends on the desired effect to be achieved by the radiation. For sterilization purposes, a dose in the range of 25 kGy is often sufficient, whereas for crosslinking doses higher than 100 kGy are typically required.

First of all, both types of radiation will have the same result and are suitable for this purpose. If you wish to switch to eBeam treatment, a first check should be carried out if the density and packing schemes of your products are suitable for eBeam treatment. Our experts will be happy to assist you here. In order to switch over, a new process validation (PQ) and parts of a microbiological validation must be conducted.

The usual cycle time at BGS is between 5 and 10 days. Depending on the volumes and utilization of the plants, we can offer you express treatment within 48 hours subject to separately agreed conditions.

Products or raw materials can be delivered as packaged units, bulk goods or coiled endless strings, profiles or pipes. BGS accepts industrial packages such as cardboard boxes on standard pallets, pallets, bulk goods in reusable containers or coiled products on standard drums. We can also accept special forms such as pipes on transport racks or other forms. Please contact our experts. For safety reasons, we will not accept flammable liquids or pressurized containers at our plants.

No, depending on the material density and energy of the electron beam, the penetration capability of the rays is up to several centimeters. This allows a reliable modification of components with substantial material thickness, which may also contain metal components.

BGS has developed plant and maintenance systems that guarantee high reliability. In most cases, redundant production facilities are available to ensure a continuous high availability of our production capacity. The reproducibility of the eBeam process is extremely high, as all parameters constitute physical characteristics which are electrically controlled and documented.

We assure you that the applied dose and processing conditions for your products meet the highest reproducibility. However, we are not able to guarantee final product properties as this depends on numerous parameters beyond our control. This includes for example processing fluctuations during production as well as fluctuations in the raw material quality or composition on which we have no influence.
