When were X-rays discovered and by whom?

X-rays were discovered by Wilhelm Conrad Roentgen on November 8, 1895.

What was the first radiograph produced and when was it taken?

The first radiograph was of Roentgen's wife's hand, Anna Bertha Roentgen, taken on December 22, 1895.

What is fluoroscopy?

Fluoroscopy is a medical imaging technique using X-rays to create real-time moving images of internal structures.

Define ionizing radiation.

Ionizing radiation has enough energy to remove tightly bound electrons from atoms, creating ions.

What are primary barriers in radiation protection?

Primary barriers are barriers directly in the path of the X-ray beam, preventing direct exposure.

What are the cardinal principles for minimizing radiation dose?

Time, Distance, and Shielding.

What is the formula for velocity?

Velocity = Displacement / Time (v = d/t)

What is the formula for acceleration?

Acceleration = Change in velocity / Time (a = Δv/t)

What is the formula for work?

Work = Force × Distance (W = Fd)

What is the formula for speed?

Speed = Distance / Time (s = d/t)

What is the formula for force?

Force = Mass × Acceleration (F = ma)

What is the formula for energy?

Energy = Force × Distance (E = Fd)
