Which of the following is the most dangerous form of radiation?

Which of the following correctly relates the becquerel to the curie?

Which material is most commonly used to shield ourselves from radioactive materials?

Identify the element formed when decays by electron capture.

Which of the following gives the correct order of the penetrating power of radiation?

Which of the following forms of radiation consists of positively charged particles?

Which of the following Greek letters is used to represent wavelength?

Identify the product formed when emits a β particle.

Identify a diagnostic technique that uses radiation from a radioisotope.

Identify the element formed when emits γ radiation.

Which of the following elements is usually studied for medical imaging by MRI scans?

Identify a radiation detector that contains a phosphor.

Boron-10 can absorb neutrons and is therefore used in control rods for nuclear reactors. After B-10 absorbs a neutron, it emits an α particle. Which isotope is produced as a result of neutron absorption followed by α emission?

Which isotope of carbon is frequently incorporated into drugs during the drug testing phase?

In which year was Becquerel awarded the Nobel Prize in Physics along with Pierre Curie and Marie Curie?
