This Polish physicist pioneered research on radioactivity and is the first woman to win a Nobel Prize, the first person and only woman to win the Nobel prize twice, and the only person to win the Nobel Prize in two different scientific fields.

Who is Marie Curie?

100

This type of radiation particle consists of 2 neutrons and 2 protons.

What is Alpha Decay?

100

This is something you should not be afraid of.

What is radiation?

100

This unit is an abbreviation for radiation absorbed dose and is a measure of the amount of energy deposited in tissue.

What is rad?

100

A form of an element with different numbers of neutrons and protons.

What is an isotope?

200

In his famous Gold Foil experiment, this New Zealand born British physicist discovered that over 95% of the mass of an atom exists in a small compact nucleus. 

Who is Ernest Rutherford?

200

This type of radioactive particle penetrates more than any other.

What is Gamma or neutron radiation?

200

This is a philosophy and regulation that is a core concept of radiation safety and is often abbreviated as ALARA. 

What is "As Low As Reasonably Achievable"?

200

This unit takes into account the relative biological effectiveness of different forms of ionizing radiation and is equivalent to the dose in rad multiplied by the quality factor Q.

What is rem?

200

This early model of the atom, proposed by J J Thomson, suggested that an atom was a positively charged sphere with small negatively charged particles called electrons that existed inside.

What is the Plum-Pudding Model?

300

The neutron was first discovered by this British physicist.

Who is James Chadwick?

300

This form of radiation particle has an overall charge of -1 or +1 depending on its type.

What is Beta radiation?

300

These are the three actions you can take to minimize your exposure to radiation.

What are Time, Distance, and Shielding?

300

These are two equivalent units of radioactivity that are both equal to 27 picocuries.

What are Becquerels and dps (disintegrations per second)?  

300

This process occurs when the Coulomb force is stronger than the nuclear force making a nucleus unstable.

What is radioactive decay?

400

Known as the "Father of modern chemistry", this French chemist named both hydrogen and oxygen  and discovered the Law of Conservation of Mass.

Who is Antoine Lavoisier?

400

This element is the resultant daughter nucleus after Cesium-137 goes through Beta decay.

What is Barium-137?

400

This is the equivalent absorbed dose the average American will experience in a year. (Either Unit)

What is 3.6 mSv or 360 mrem?

400

This is the equivalent absorbed dose (in Sievert) when a 1 kg rabbit is irradiated with 100 Joules of gamma radiation.

What is 100 Sv?

400

This atomic model proposed that electrons orbit the nucleus of an atom in discrete energy levels.

What is the Bohr Model?

500

While this physicist was the father of the modern quantum mechanical theory of atoms, he is more commonly known in relation to a common household pet.

Who is Erwin Schrodinger?

500

After going through alpha and then beta decay decay, this commonly found unstable metal becomes Protactium-234.

What is Uranium-238?

500

These are three common sources of radiation found in a house.

What are bananas, radon gas, cosmic background, smoke detectors, brazil nuts, tobacco, CRT TVs, etc?

500

After swallowing a 2 Bq Radium source of alpha radiation, a 100 g mouse will experience this equivalent absorbed dose (in rem) over 10 seconds if each disintegration produces 5 ergs of radiation energy.

What is 20 rem?

500

While we used to believe the atom was the smallest particle we now know they are actually made of elementary particles which belong to these two families. Hint: the two types of fermions

What are quarks and leptons?
