DESCRIPTION

The radioactive decay tanks designed by Lemer Pax are intended for the storage of radioactive waste during decay periods before their release into the normal wastewater circuit. From the shielded chambers for Iodine-131 radiation therapy and all RadioPharmaceutical Therapy (RPT) treatments in general. As well as from the laboratories, sinks, showers and hot toilets of the nuclear medicine service.

The size and capacity of the tanks can be adapted to meet the needs of the user services with individual tanks from 100 to 15,000 litres.

In order to adapt to the geometry of the premises, the design of these tanks is customised for perfect integration and ergonomic installation in premises of all sizes. The customised manufacture of the tanks allows for a wide variety of designs in size and shape.

Materials used are specifically designed to withstand radiation and offer a very efficient sealing properties, as well as easy maintenance and decontamination.

The monitoring of the filling level of each tank is optimised by a touch screen reporting system and a configurable alarm, according to the applications and the evacuation rules defined by the services.

Decay tanks: a specific secure monitoring system

Lemer Pax’s dedicated teams manufacture the entire system and also perform installationand maintenance.

The tested and patented specific secure monitoring system for the management of radioactive waste is proposed to correspond to the recommendations of the ASNR (French Authority for Nuclear Safety and Radiation Protection) in order to guarantee long-lasting and trouble-free use. Depending on the options selected, this management unit can automate the rotation of the valves remotely, as well as monitor and display the activity measurements before discharge, without requiring manual action by the users, thus ensuring a high level of radiation protection.

Upgrades – Retrofits

Based on our vast experience and extensive catalogue of radiation protection solutions, Lemer Pax can propose a solution perfectly tailored to any setting. Lemer Pax renovates old systems to meet the latest standards set by the ASNR, proposing automated control cabinets with sensors and touchscreens to ensure precise management of tanks contents and end-of-fill times, all connected to the wastewater system.

Retrofitting containment tray by designing custom trays made from radiation resistant materials offers an effective solution when upgrading storage facilities. These trays are tailored to meet specific requirements in terms of capacity and size, enabling optimum customisation for each project. This tailor-made approach offers the considerable advantage of a short turnaround time, significantly reducing service downtime.

REGULATORY FOCUS – SPECIFIC TO¹⁷⁷Lu:

Within the framework of the “Circular letter on the changes in the conditions of authorisation of nuclear medicine services by the ASN for the possession and use of lutetium-177”, the connection of toilets to a decay tank is recommended for all nuclear medicine services carrying out vectorised internal radiation therapy treatments with ¹⁷⁷Lu labelled radiopharmaceuticals.

The urine of treated patients should be collected for at least the first 6 hours after administration of the radioactive drug, even if the service does not have a shielded chamber.
