Patent number: 10811156Abstract: This disclosure pertains to a gamma radiation source, including enriched Iridium-191 and Boron-11. Some embodiments may include alloying. Some embodiments may include sintering. The resulting disk, adapted for radiological sources, typically has a reduced attenuation and a reduced cost, due to the reduction in the use of Iridium-191. Substitutes for boron include aluminum, silicon, vanadium, titanium, nickel, platinum, phosphorus and/or combinations thereof.Type: GrantFiled: May 8, 2015Date of Patent: October 20, 2020Assignee: QSA GLOBAL INC.Inventors: Mark G.

Patent number: 6415309Abstract: For generating random numbers, the output of a random pulse generator having a radioactive source is monitored and the number of decay events detected counted over a predetermined time period. The number of detected events is then compared to one or more selected numbers and a first signal, for example binary “1”, is produced where the detected count is equal to the one or more selected numbers and a second signal, binary “0”, is produced where the detected count does not equal the one or more selected numbers. The time period is determined so that the probability of the first signal being generated is equal to the probability of the second signal being generated. In this way a truly random number can be generated by repetition of the method steps described above producing a stream of binary “1's” and “0's”. Virtually no radioactivity is required for the apparatus to operate and it can in principle be integrated into a single chip.Type: GrantFiled: June 4, 1999Date of Patent: July 2, 2002Inventor: Mark G.
