2. In what country did the Curies do their research? France to
review the material about the Curies work, go to packet 9 website
& click on pictoral story of Marie Curie. (It WILL be on
quiz!)
Slide 4
3. What type of nuclear reaction is responsible for creating
the elements? A. natural decay B. induced C. electron capture D.
fission E. fusion fusion occurs in stars, which turn small elements
into larger ones
Slide 5
4. Which does NOT describe a property of vaseline glass? A. its
banned by the government B. it has a yellow-green color C. it glows
under a UV blacklight D. its radioactive Vaseline glass gets its
color & radioactivity from uranium. It is now a sought-after
collector item. From hot or not demo day.
Slide 6
5. In the Radio Bikini video, how many bombs were detonated
near Bikini Island? two #1 was above the target ships. #2 was below
the water. (the H-bomb was also tested there, 10 years later)
Slide 7
6. In a nuclear power plant, the purpose of H 2 O is to
I.protect workers from radiation II.cool the reactor III. turn the
turbines A. only I. E. II. and III. B. only II. F. I. and III. C.
only III. G. I, II, and III D. I. and II. H. none of them I.Fuel
rods are stored under water for safety. II. Water is used to cool
the reactor core. III. Water (steam) under pressure turns turbines.
See WS 9.6
Slide 8
7. Why did the Fiesta company stop using uranium in their
dinnerware? A. it became too expensive to mine for the uranium B.
too many workers were developing cancer C. the government used the
uranium for bombs D. Mr. Andersons students kept stealing the
plates & sold them to fund the Don Showalter fun club. This
forced the Fiesta company to use a different type of glazing. From
hot or not demos.
Slide 9
8. The general idea of Einsteins equation E = mc 2 is that A. a
small amount of mass can be changed into a large amount of energy
B. a small amount of energy can be changed into a large amount of
mass C. energy and mass are equally interchangeable D. energy and
mass are not interchangeable This is why nuclear energy is so
efficient. See WS 9.7.
Slide 10
9. Which would have the highest ratio of C-14 to C-12? A. an
elm tree, chopped down 1,000 years ago B. a limestone boulder, age
as old as Earth C. a newborn infant D. a wool blanket, 15,000 years
old Everything living has the SAME C-14 to C-12 ratio. This ratio
never changes until death. C-14 dating is a big part of quiz. See
WS 9.4
Slide 11
10. What are some application of nuclear fusion? I.nuclear
power plants II.nuclear weapons III. medical scanners A. only I. E.
II. and III. B. only II. F. I. and III. C. only III. G. I, II, and
III D. I. and II. H. none of them I.Were still many decades away
from fusion reactors. II. The hydrogen fusion bomb. Never used in
war. III. Um, I hope not! See class notes: applications of
fusion.

US that had a parital meltdown, scared public, but no environmental
damage: Chernobyl Three Mile Island

will be its daughter? hint: youll need to look it up on your good
periodic table positron decay 9 18 F 0 e + 18 O +1 8 from WS 9.2
writing balanced nuclear equations

presumed dead from radiation illness B. in 1988, they were granted
homestead access to return to their island C. mostly confined to
Internment camps in American Somoa D. living in settlements around
the Marshall Islands E. the only 9 survivors are living in Mr.

Slide 18
18. Someone finds a 40 year old thorium (an alpha emitter)
coated lantern mantle in their garage. What substance(s) would be
present on it today? I.thorium II. uranium III. radium IV.
americium A. all are possible D. I and III B. only I & II E. II

increase an atomic # to form 92 U or 95 Am
Slide 19
19. radon-222 undergoes how many alpha and beta decays to
become astatine-218? from WS 9.2: writing balanced nucelar
equations 222 Rn 4 He + 218 Po 86 2 84 218 Po 0 e - + 218 At 84 85
