A person should undergo Xrays as often an they are necessary, because the risk-to-benefit ratio is usually very far in favor of the benefit.
As an example of this idea of risk-to-benefit ratio, lets take getting into a car.
There is always a risk to getting into a car. After all, they move quickly, slide on slippery roads, and hurl towards (and potentially ...

After looking (without result!) at loads of pages returned from a Bing search for BNCT, I hit upon searching for:
FLUENTAL moderator
The first reference I looked at was:
Use of TEPCs for characterising BNCT Beams
but there is no reference to the manufacturer.
However, the opening chapter of:
Chemical aspects on the final disposal of irradiated
reads:...

You most definitely do not want to be in an MRI machine during an earthquake. The superconducting magnets in an MRI scanner are cooled by liquid helium. If the cooling system is damaged and there is a leak, this could be very bad for you.
I have not seen what is in the yellow folder, but earthquakes present a particularly dangerous situation for MRI ...

Do nothing, stay inside the MRI machine.
I never performed MRI scan in the past but I had experience of several quite big earthquakes within the last 10 years. So I provide my thought on this for your reference.
I have to say that you probably already in the safest place during an earth quake in a building for two reasons:
1) rooms for big scanners are ...

Tests that can help detect ovarian cancer are pelvic exams, transvaginal ultrasounds, and some blood tests. 1 At least the first two are generally handled by gynecologist, and they are the specialists that know mist about ovarian cancer, so if possible, your wife should probably talk to one. If your wife doesn't have a gynecologist, a general practitioner (I ...

Via the UCLA Brain Mapping Center, in the event of (emphasis and formatting added):
Non-Fire Facility Emergencies
Unscheduled Power Shutdowns
Earthquakes
Magnet Quench (catastrophic boil-off of helium)
Water Leaks

Instructions are:
Perform a routine electrical shutdown, or if circumstances ...

"Effective dose" is not a physical quantity, but a calculated summary value meant to evaluate the risk of some radiation exposure to other sources and to set occupational limits.
From Fisher & Fahey 2017:
Effective dose is a mathematical construct, concept, or surrogate of risk, used in radiation protection as the basis for calculating annual ...

The authors did an experiment with two independent variables: group and region. The groups are "schizophrenia" and "no schizophrenia" (controls). The a priori regions were the frontal cortex, anterior cingulate, and hippocampus (they also had exploratory analyses of other regions).
Their study was a PET scan, measuring [11C]UCB-J as a marker for synaptic ...

Fetal gender determination is suprisingly accurate, according to this study: Accuracy of sonographic fetal gender determination: predictions made by sonographers during routine obstetric ultrasound scans
The results state the following:
Results confirmed 100% accuracy in predictions made after 14 weeks
gestation. The overall success rate in the first ...

Assuming you're in the U.S. and the jammer is mounted atop your building, you need to do an environmental assessment if your transmit power is over 1000 watts. However, as Carey Gregory mentioned, if you're jamming signals in the U.S., you have other legal problems (and you will be jamming signals at 1000 watts). If you're planning on mounting the jammer in ...

It is difficult to judge, as we don’t know whether your fracture resulted from an acute direct trauma or whether it is a so called “stress fracture” (due either to an abrupt increase in activity or to chronic overload).
While most of the acute fractures (in particular shaft fractures) are visible on lateral view Rx (+/- oblique or modified lateral views Rx)...
