CR Series of Shielding Containers LB 7440,LB7442,LB7444

Product catalog summary

Overview: The document details the CR Series of Shielding Containers (models LB 7440, LB 7442, LB 7444) designed for encapsulated radioactive sources used in industrial applications. These containers ensure safe handling and transportation of radioactive materials by providing robust shielding and secure mechanisms.

Specifications: The shielding containers are constructed with a cast-steel lead-filled housing and feature a lockable shutter mechanism to control the radiation outlet channel. The models are equipped with a stainless steel source capsule and holder, ensuring protection against mechanical damage and environmental influences. The containers are designed to meet safety standards by reducing radiation exposure to safe levels for personnel.

Options: The containers offer several optional features, including a pneumatic shutter mechanism that is fail-safe in case of pressure drops, and indication of the shutter position via limit switches or proximity initiators. For extreme conditions, a rubber cover with a Perspex window is available to protect the locking mechanism.

Design Features: The CR series is noted for its improved corrosion resistance, with components such as the housing, outlet channel cover plate, and handle made from stainless steel. The containers can be locked using a padlock, and the handle is designed to prevent unauthorized access.

Model Variations: The document specifies different models for various applications: models with suffix 'F' are used for level measurements with a larger radiation outlet diameter, while models with suffix 'D' are used for density measurements with a smaller radiation beam diameter.

Technical Data: The document provides detailed technical data, including shielding thickness, attenuation factors for different radioactive isotopes (60Co and 137Cs), and dose rates at various distances from the shielding surface. The operating temperature for all models is up to 200°C.

Installation and Licensing: The containers are designed for flange or bracket mounting, with specific dimensions and weights provided for each model. The document notes that the pneumatic shutter mechanism is not available in the USA, and the containers are licensed by the NRC for operation in the USA.

Shieldings for Point Sources Encapsulated radioactive sources are used for industrial applications. The radioactive substance is contained in a tightly sealed stainless steel Source Capsule, sometimes with several walls. The Source Capsule is mounted in a shielding Housing using a Source Holder. This shielding must meet several criteria: • The radiation must be shielded to a safe level for the operating • The radiation outlet channel must be lockable for transport and during • The source capsule must be protec- ted from both mechanical damage and from environmental influences. The shielding container...
