You planned to add 10 µL to a tube but accidentally ejected the entire pipette tip contents onto the bench

What is “I guess we’re starting that experiment over”

200

This principle minimizes radiation exposure by keeping doses ALARA. What does ALARA stand for?

As Low As Reasonably Achievable

200

This small molecule ACE2 activator has been shown to improve survival following radiation exposure in rodent models

What is Diminazene Aceturate (DIZE)

200

This radiation syndrome is caused by severe damage to bone marrow

What is the hematopoietic syndrome

200

This model irradiates the body while shielding specific organs such as bone marrow to study GI injury

What is partial body irradiation

200

Your western blot bands look perfect. That is, until you realize the samples were loaded in the wrong order.

What is “label your tubes better next time”

300

These are packets of electromagnetic energy commonly used in medical radiation therapy
