What is the main difference between an isotope and a radioisotope?
isotopes are stable (they do not decay), and radioisotopes decay and produce radiation
Which statement best describes beta particles?

B- They are charged particles, either an electron or a positron
C- They are a type of electromagnetic radiation
D- They are stable particles
B- They are charged particles, wither an electron or a positron
Thick dense shielding must be used to protect a worker from which of the following types of radiation?
A- Alpha particles and gamma radiation
B- Beta particles and X-rays
C- Gamma radiation and X-rays
D- Alpha and beta particles
C- Gamma radiation and X-rays
What type of radiation does Iodine-125 produce?
Gamma Radiation
What type of radiation does Carbon-14 produce?
Beta particle
What type of radiation does Fluorine-18 produce?
Beta particle
What type of radiation does Phosphorus-32 produce?
Beta particle
What type of radiation does Tritium produce?
Beta particle
What type of radiation does Americium-241 produce?
Alpha particle
Why is it generally considered best to use powdered rather than powder-free medial exam gloves?
Because the manufacturing of powder-free gloves may weaken the material and lead to more frequent pin holes and tears
Which class of biosafety cabinets offers the most protection to personnel?
A- Class I
B- Class II
C- Class III
D- All of the above
C- Class III
