A radioactive seed handling device for handling a number of radioactive seeds. The device includes a first tubular section having a first lumen with a first diameter larger than the seed diameter for receiving the seed and a second tubular section coupled to the first tubular section and having a second lumen with a second diameter smaller than the seed diameter for preventing seeds from entering the second lumen. An overlapping portion of the second tubular section is located within the first l...

A method for removing radioactive contaminants from a given surface. An aqueous solution having a wetting agent and a complex substituted keto-amine is provided. The solution is left on the surface for a time sufficient to remove the radioactive contaminants into the aqueous solution which is then removed. Depending on the type and condition of the surface, a concentrated acid may be added to the aqueous solution to aid in the contaminant removal process. In such a case, a pH of less than 3.0, a...

A precision accelerometer is provided which is capable of measuring linear accelerations along three axes. The accelerometer incorporates a self-charging radioactive particle as the inertial acceleration sensing mass. The particle is contained in an evacuated cubical chamber, and the position of the particle within the chamber is established by the differential between the mean number of emitted charged particles detected at the opposite walls of the chamber, whenever the particle moves from a c...

A radioactive member for use in brachytherapy comprising a molded elongate, bioabsorbable carrier material with spaced radioactive sources disposed therein, and methods for the manufacture thereof. The radioactive members may be used in the treatment of, for example, prostate cancer.

Methods are discussed for treating liquid and particulate radioactive waste materials for transportation and storage. The disclosed methods include the reading of an ohmmeter connected across a pair of separate and mutually insulated liquid level sensing electrical contacts arranged to contact the surface of a mixture of radioactive waste materials and a setting agent when a container is filled to a predetermined level with that mixture and determining from variations in the resistance between t...

A wiring substrate section 2 is provided between a radiation detecting section 1, which is formed of a scintillator 10 and a PD array 15, and signal processing elements 30 and 32 for processing a detected signal outputted from the PD array 15, and the wiring substrate section 2 has a wiring substrate 20 which is formed of a glass material having a radiation shielding function and in which a conductive member 21 serving as a conduction path for guiding the detected signal therethrough is provided...

An apparatus for fixing radioactive or toxic waste has an extruder including a mixing mechanism for intermingling and advancing the waste and a carrier material introduced into the extruder. The extruder has a heating zone with which there communicates a vapor outlet device having an observation window. Within the vapor outlet device there is disposed an arrangement for cleaning the window and an arrangement for removing deposits from those locations of the vapor outlet device that are adjacent ...

New radioactive compounds are disclosed which are useful for labeling proteins and the like for radioimmunoassay techniques. These compounds are imido esters of radioactive substituted hydroxy or alkoxy phenyls.

A depository for storing radioactive waste is comprised of a material such as natural rock, magmatic rock, or concrete. The construction body has an interior storage chamber. The size and the wall thickness of the construction body prevent emission of radioactive radiation during a projected storage time of several thousand years. The construction body is designed to provide a free, stable support on a concave to flat ground surface so that a displacement of the construction body due to tectonic...
