Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
123 words
THE METHOD OF MEASURING THE RADIOACTIVITY OF AN INSERT FISSION GAS IN A SAMPLE OF A MIXTURE OF GASES, COMPRISING THE STEPS: REMOVING ALL PARTICULATE MATTER FROM SAID SAMPLE, THEREBY OBTAINING A PURIFIED SAMPLE; STORING THE PURIFIED SAMPLE IN AN AIRTIGHT RESILIENTLYEXPANDABLE CONTAINER FOR A PREDETERMINED TIME; EXHAUSTING THE CONTENTS OF SAID COLLAPSIBLE CONTAINER THROUGH A COLLECTING MEANS WHEREBY PARTICULATE DAUGHTER PRODUCTS RESULTING FROM DECAY EVENTS OCCURRING WITHIN SAID CONTAINER ARE COLLECTED THEREIN; AND MEASURING THE RADIOACTIVITY OF THE COLLECTING MEANS AND THE COLLAPSED CONTAINER TO DETERMINE THE AMOUNT OF THE PARTICULATE DAUGHTER PRESENT IN THE EXHAUST MIXTURE; WHEREBY THE QUALITY OF RADIOACTIVE INERT FISSION GAS PRESENT IN THE SAMPLE CAN BE DETERMINED BY THE RADIOACTIVITY DECAY CHARACTERISTICS OF THE INERT FISSION GAS.
