US 11,029,417 B2 · Radioactivity measurement method and radioactivity measurement system using data expansion

Abstract

The present invention relates to a radioactivity measurement method and a radioactivity measurement system using data expansion. A radioactivity measurement method using data expansion according to the present invention comprises the steps of: measuring radioactivity while performing energy scanning and temporal scanning; preparing a database from a time-energy-related data set obtained in result of the scanning; expanding the database by means of random distribution fitting; and obtaining a radioactivity measurement value of desired time from the database.

Claims7

Dependent claims

A radioactivity measurement method using extended data, the method comprising:

measuring radioactivity while performing energy scanning and time scanning;
generating database from data sets about time-energy relationships obtained from the time scanning and energy scanning during a first time period;
extending the database using random distribution fitting over the first time period to obtain an extended database;
and
estimating, from the extended database, a nuclide-based radioactivity decay characteristic for a second time period after the first period time.
