Forensic Science and Ion Beam Analysis

What inspired Dr. Melanie Bailey to pursue a career in forensic science?

• Her desire to become a detective

• Her childhood love for cookies

• Her interest in solving crimes with science

• Her fascination with chemistry

What is the primary function of the Ion Beam Accelerator in Dr. Bailey's research?

• To detect fingerprints on surfaces

• To accelerate particles to the speed of light

• To create new elements

• To analyze the elemental composition of samples

Which element was unexpectedly found in the gunshot residue samples?

• Iron

• Lead

• Copper

• Sodium

What is a limitation of using electron microscopy for gunshot residue analysis?

• It cannot detect any elements

• It requires a large sample size

• It is less sensitive than the ion beam technique

• It is too expensive

How does Dr. Bailey's technique help in identifying different ammunition powders?

• By detecting the color of the powder

• By analyzing the shape of the particles

• By identifying unique elemental compositions

• By measuring the weight of the powder

What problem related to gunshot residue can Dr. Bailey's technique address?

• The difficulty in collecting samples

• The issue of contamination

• The inability to detect lead

• The high cost of analysis

What other forensic application does Dr. Bailey explore with the ion beam?

• Identifying shoe prints

• Detecting blood types

• Examining textile fibers

• Analyzing DNA sequences

What can Dr. Bailey potentially determine from the chemical composition of fingerprints?

• The person's age

• The person's diet

• Whether the person is a smoker or drug user

• The person's blood type

What does Dr. Bailey hope to achieve with her forensic research?

• To develop new types of ammunition

• To become a famous scientist

• To strengthen the value of evidence in court

• To replace all traditional forensic methods

What gives Dr. Bailey more satisfaction than her childhood interest in cookies?

• Solving crimes with physics

• Baking new recipes

• Teaching physics to students

• Collecting rare elements
