sealed radioactive source

Sealed radioactive sources used to be called 'closed' sources.

• Nuclear gauges, which incorporate sealed radioactive sources, used in measurement applications.

Sealed radioactive sources are sometimes lost or mislaid.

It encourages States to institute means for ensuring that sealed radioactive sources are managed safely and securely.

Notes for guidance on the clinical administration of radiopharmaceuticals and use of sealed radioactive sources.

Sealed radioactive sources have a structure which prevents radioactive material from leaking during normal use.

Sealed radioactive sources may be used for radiography, well logging or in liquid level and density gauges.

Officials said countries using sealed radioactive sources often don't have appropriate storage and security infrastructure in place to manage spent radioactive material.

States should have in place an effective national legislative and regulatory system of control over sealed radioactive sources and radioactive material.

The Commission is of the opinion that Article 7 provides for sufficient minimum requirements to ensure effective control over high activity sealed radioactive sources.

Using actinides in nuclear fuel, sealed radioactive sources or advanced materials such as self-glowing crystals has many potential benefits.

Sealed radioactive sources are widely used in industry, medicine and research and are often small and mobile.

Scope This Directive applies to high-activity sealed radioactive sources.

Brachytherapy involves the placement of sealed radioactive sources within the body to deliver a controlled radiation dose to the tumour.

Sealed radioactive sources are routinely used in formation evaluation of both hydraulically fractured and non-fracked wells.

Occasionally, radiotherapy may take the form of brachytherapy, which involves the surgical implantation of a sealed radioactive source.

Part 2 Regulatory Controls Section 7, covers "the responsibilities of owners of sealed radioactive sources and certain radiation apparatus".

Consequently there were already basic Community standards on this subject (Directive 96/29/Euratom) containing rules on high-activity sealed radioactive sources.

States should ensure that the possession, remanufacturing or disposal of disused sealed radioactive sources takes place in a safe manner, P-PO9:

In June 2008, a cesium-137 sealed radioactive source was found among scrap metal sold to a scrap dealer in Ayutthaya Province.

Use of chemically unstable forms of actinides in MOX and sealed radioactive sources is not appropriate by modern safety standards.

After the adoption of the Council Directive on the control of high activity sealed radioactive sources, Member States should ensure its fast implementation at national level.

Current efforts to control high-activity sealed radioactive sources are unlikely to change this trend in the near future since recovered and recycled scrap can be 40 years or more old.

You must display a copy of your environmental permit on your business premises, unless it relates to sealed radioactive sources or it is otherwise subject to national security restrictions.

This can be delivered by medical linear accelerators (linacs) or specially-designed teletherapy machines containing sealed radioactive sources, both of which are located in specially-designed and well shielded facilities.
