摘要:
An apparatus for measuring the density or the like of an object from the level of transmission through the object of gamma rays having different energy levels which are transmitted at the object by a gamma source having a predetermined solid angle of transmission. A collimator collimates gamma transmitted through the object and a scintillator generates light corresponding to the output of the collimator. Plural photomultipliers generate position-dependent electrical signals corresponding to the light generated by an incident gamma ray photon to the scintillator. A calculating circuit generates a density spectrum for the object from the position-dependent electrical signals by integrating the position-dependent electrical signals corresponding to each of the incident gamma ray photons to the scintillator.
摘要:
The present invention provides a combination product which comprises: (1) a polyaldehyde obtained by introducing an aldehyde group into a branched glucose in a β-1,3-glucan, and (2) a polyamine obtained by increasing the molecular weight of a poly-L-lysine. The combination product according to the present invention is useful as a material for a tissue adhesive hydrogel which can be used as a hemostatic agent or the like which exhibits low risks for viral infections and the like, high biodegradability and biocompatibility, excellent safety, a good adhesion rate and a good adhesion strength.

摘要:
An ionization chamber can stably measure a weak ionizing radiation with high sensitivity. The ionization chamber comprises an electrically conductive charge collecting electrode having a magnetic substance or a permanent magnet; an electromagnet for positioning the charge collecting electrode in non-contact with the other part of the ionization chamber; a position sensor for detecting the position of the charge collecting electrode; a circuit for feedback-controlling the magnetic force of the electromagnet to maintain the charge collecting electrode at the substantially same position; and ionization current detecting circuit for detecting an ionization current collected at the charge collecting electrode by ionization due to radiation applied to the ionization chamber.
