Disclosed is a ceramic shielding apparatus including at least one shield made of a ceramic material and provided inside or outside an X-ray tube to shield radiation; and supports configured to support the shield. According to such a configuration, disadvantages of conventional shielding materials such as lead can be addressed, so that a shield apparatus having excellent shielding properties while being harmless to the human body can be provided.

The invention relates to a combination of containers intended to discharge radioactive substances into the earth's magma by pouring them into lava lakes, and to a method for using these containers. The radioactive substances are preferably placed in ovoid waste containers that are loaded into a transport container and discharged therewith into a lava lake. The transport container decomposes by melting following a first immersion at a given depth and releases the waste containers, which continue to move downwards.

An apparatus includes a splash shield incorporating a clear viewing area, a vacuum manifold, the vacuum manifold adapted to releasably engage the splash shield, and a link emanating from the vacuum manifold, the link configured to attach to a vacuum system wherein application of a vacuum creates a laminar flow to draw vapor away from the splash shield.
