This Health Physics Corner discusses Fluorine-18 production in a PET cyclotron. How much Fluorine-18 activity can be generated using a 3-hour irradiation? What’s the approximate unshielded effective dose rate at 3 metres?
In this instalment of the Health Physics (HP) Corner, Jeff is checking the activity estimate for monazite ore, which nominally contains 10 MBq of Th-232. If the ambient dose equivalent gamma constant for Th-232 is essentially zero, why is the measurement at 10 cm more than 1,000 times as high as you might expect?
In this instalment of the Health Physics (HP) Corner, Jeff explores dead time—the period after the recording of a particle or pulse when a detector is unable to record another.
For years, the Health Physics (HP) Corner was a regular feature in the CRPA Bulletin. It drifted away in 2017, but we are very excited to see it resurrected by Jeff Sandeman!. In this first installment, Jeff carries on from the Canadian Nuclear Safety Commission (CNSC) licensee outreach presentation on contamination monitoring and runs through some verification calculations and examples.
