What is an Alpha particle?
As a nucleus emits this particle,
Its atomic number decreases by
2 and its mass number decreases
By 4.
Row 1, Col 1
What is a natural transmutation?
This is when an element changes
Naturally to another element.
1,2
What are radioactive substances?
These substances decay at a
Constant rate that is not dependent
On temperature, pressure, or
Concentration.
1,3
What are Radioisotopes?
These isotopes have many
applications in
Industry, medicine, and
Research.
1,4
What is a Beta particle?
When a nucleus emits this
Particle, the charge on the
Nucleus increases by 1 and the
Atomic number increases by 1.
2,1
What is Fusion Reaction?
This is a reaction that involves
The combining of light nuclei
To produce a heavier nucleus.
2,2
What is a half-life?
The time it takes for half of the
Atoms in a given sample of an
Atom to decay.
2,3
What is a Tracer?
Any radioisotope used to follow
the path of a material in a
System.
2,4
What is a Positron particle?
When a nucleus emits this
Particle, which has a charge of
+1, the charge on the nucleus
Decreases by 1 and thus the
Atomic number decreases by 1.
3,1
What is Fission?
As a result of this process,
The nucleus produced by the
Capture of a neutron is unstable
And it quickly splits.
3,2
What is a Geiger Counter?
This device can be used to record
individual decay events.
3,3
What are Radioisotopes?
Certain types are quickly
Eliminated from the body and
Have short half-lives that are
Important as tracers in
Medical diagnosis.
3,4
What are Gamma rays?
Almost all nuclear decay also
Releases some energy in the form
Of these rays.
4,1
What is Fusion?
The most common example of
This process occurs in the sun
Where hydrogen nuclei react in
A series to produce helium
Nuclei.
4,2
What is a half-life?
The initial amount of a
Substance can be determined
By this, along with the amount
Remaining and the time passed.
4,3
What is the accident at Chernobyl?
This incident in 1986 caused a
Nuclear meltdown due to unstable
Radioisotopes.
