What is a sealed radiation source container?
REVISS transport containers are large well-shielded flasks weighing 3.5 to 14 metric tonnes, which are used to transport sealed radiation sources from the point of manufacture to our warehouse and on to our customers. They use heavy lead or depleted uranium to shield the environment from gamma radiation. They are robustly designed to international standards, to withstand potential accident conditions. Part of the design process is to test by dropping them from a height of 9m at a temperature of -200°C onto a steel spike on a concrete floor. In transit they are bolted onto a truck base. They cannot be breached in normal use or road accident conditions and they are never left unattended outside the REVISS warehouse. They are opened under water to shield the operator from gamma radiation emitted by the sealed sources contained inside. Once the sources are removed from the container it is safe to handle the container without special procedures.
