ALARA Principle and what is it?
• ALARA" is an acronym for "As Low As Reasonably
Achievable".
12
• How is ALARA used in the practice of radiation
protection?
– ALARA is a basic radiation protection concept or
philosophy.
– It is an application of the "Linear No Threshold
Hypothesis," which assumes that there is no "safe" dose of
radiation.
– Under this assumption, the probability for harmful
biological effects increases with increased radiation dose,
no matter how small.
– Therefore, it is important to keep radiation doses to
affected populations (for example, radiation workers,
minors, visitors, students, members of the general public,
etc.) as low as is reasonably achievable.
13
• Where are ALARA principles utilized?
– ALARA principles can be utilized in an infinite
number of situations.
• For example, the proper design of a nuclear facility
depends on ALARA considerations (e.g., can the addition
of more shielding to an area be justified in terms of the
lower doses it will achieve?).
• In addition, designing an x-ray facility for medical
applications requires consideration of the amount of
shielding needed to ensure that individuals located near
the facility (e.g., on the other side of the wall from the xray unit) do not receive any more dose than is really
necessary during operation of the x-ray device.

Types of Exposure & Health
Effects
• Acute Dose - Deterministic
– Large radiation dose in a short period of time
– Large doses may result in observable health effects
• Early: Nausea & vomiting
• Hair loss, fatigue, & medical complications
• Burns and wounds heal slowly
– Examples: medical exposures and
accidental exposure to sealed sources
• Chronic Dose - Stochastic

Inhalation
Examples: Background Radiation and
Internal Deposition
24
Deterministic (Acute) Effects
• Examples will include:
– radiation burns (skin
reddening),
– hair loss
– cataracts and radiation
sickness (nausea,
vomiting and
diarrhea).
•
All of these effects results
from acute high doses of
radiation to either a part of
the body or the whole body.
For whole body exposure it
is generally thought that an
absorbed dose of between
3-5 Gy will cause 50% of
those exposed to die within
30 days if medical
intervention is not given.
This is known as the LD-50
dose.
25
Stochastic (Chronic) Effects
• Cancer
• Leukemia
• Genetic effects
• Cataracts
26
Biological effects of radiation to
humans.

36
Terms and Definitions
• Atom
Basic component of matter. An atom is the smallest
part of an element having all the chemical properties
of that element. An atom consists of a nucleus (that
contains protons and neutrons) and surrounding
electrons.
• Nucleus
The central part of an atom that contains protons
and neutrons. The number of protons uniquely
defines the chemical element.
• Proton
One of three basic particles in an atom. Protons are
located in the atom nucleus, have a positive electrical
charge, and each has mass about equal to a neutron.37
Terms and Definitions
• Neutron
One of three basic particles in all atoms except
hydrogen. Neutrons are located in the atom nucleus,
are electrically neutral, and each has mass about
equal to a proton.
• Electron
One of three basic particles in an atom. The electron
has a negative electrical charge, orbits the atom
nucleus, and has very little mass compared to the
nucleus.
• Quark
basic building block of protons, neutrons, other
baryons, and mesons.
38
Terms and Definitions
• Isotope: atomic nuclei having same number
of protons but different numbers of neutrons.
• Alpha particle: positively- charged particles
consisting of two protons and two neutrons
emitted by radioactive materials.
• Beta particle: high speed electron emitted by
a radioactive nucleus in beta decay.
• Gamma particle: high energy photon emitted
by a radioactive nucleus.
39
Terms and Definitions
• X ray: high- energy photons; high- frequency,
short-wavelength electromagnetic waves.
• Ionizing radiation particles or waves that can
remove electrons from atoms, molecules, or
atoms in a solid.
• Radioactivity Spontaneous emission of radiation
from the unstable nucleus of an atom.
• Radioactive isotope Element that emits ionizing
radiation when it decays. Radioactive isotopes are
commonly used in science, industry, and medicine.
40
Definitions
• Background radiation: Radiation arising from
natural sources always present in the
environment, including solar and cosmic
radiation from outer space and naturally
radioactive elements in the atmosphere, the
ground, building materials, and the human
body.
• Contamination: Act of making a substance
impure, radioactive, or unclean.
41
Definitions
• Becquerel (Bq): Measure of the rate of decay of a
radioactive substance. One Bq is 1 disintegration per
second. The human body has thousands of
disintegrations from the presence of potassium-40.
• Curie (Ci): Unit of measure of the rate of decay of a
radioactive material. One Curie is the radioactive
intensity of one gram of radium--37 billion
disintegrations per second.
• Half-life: Time for a radioactive substance to lose
half of its activity due to radioactive decay. At the
end of one half-life, 50% of the original radioactive
material has decayed.
42
Definitions
• Nuclear energy : Energy, usually in the form of heat or
electricity, produced by the process of nuclear fission
within a nuclear reactor. The coolant that removes the
heat from the nuclear reactor is normally used to boil
water, and the resultant steam drives steam turbines
that rotate electrical generators. Nuclear energy is also
produced when two nuclei fuse.
• Nuclear Reactor: Any of several devices in which a
chain reaction is initiated and controlled, with the
resulting heat typically used for power generation and
the neutrons and fission products used for military,
experimental, and medical purposes. Also called
atomic reactor.
43
Definitions
• Particle accelerator: A device, such as a
cyclotron or linear accelerator, that accelerates
charged subatomic particles or nuclei to high
energies. Also called atom smasher.
• Rad: Basic unit of absorbed dose of ionizing
radiation.
• Gray: unit of absorbed dose of ionizing
radiation.
• Radiation: Particles and electromagnetic rays
(waves) emitted from the center of an atom
during radioactive disintegration.
44
Definitions
• Radon: Heavy, natural, radioactive gas formed by the
radioactive decay of radium, a decay product of uranium. Its
atomic number is 86 and its atomic weight is 222. It’s symbol is
Rn.
• rem: (Roentgen equivalent man), a unit used in radiation
protection to measure the amount of damage to human tissue
from a dose of ionizing radiation. An average American receives
about 0.360 rems of radiation per year.
• Sievert : Unit that measures the effect of radiation on the body.
"Sievert" replaces the old unit "REM" (Radiation Equivalent
Man), a calculated number based on dose and the body organ
(e.g. a dose on your eye would give a different number from the
same dose on the liver). 1 REM = 10 milliSieverts (mSv).

Types of particle accelerators
• Electron-positron colliders
– LEP collides together bunches of electrons with
bunches of positrons, as they travel in opposite
directions round a ring 27km in circumference, at
velocities close to the speed of light. When the
bunches of particles meet, some electrons and
positrons annihilate, creating, for a fraction of a
second, bursts of high energy which echo the
state of the early Universe, but are quite
harmless.
51
Types of Particle accelerators
• Hadron colliders
– Two beams of subatomic particles called
'hadrons' – either protons or lead ions – will
travel in opposite directions inside the
circular accelerator, gaining energy with
every lap. Physicists will use the LHC to
recreate the conditions just after the Big
Bang, by colliding the two beams head-on
at very high energy

57
Albert Einstein (1879-1955)
• 1905, produced the theory of relativity
(E=mc2)

58
Albert Einstein (1879-1955)
• Experimenters have carried extremely
accurate atomic clocks on high-speed jets on
around-the-world journeys. And when they
compared these clocks to the extremely
accurate clocks they left at home, the
traveling clock had indeed gone slower and
lost time. But by very little.
59
Albert Einstein (1879-1955)
• received the 1921 Nobel Prize for work in
mathematical physics & stating the law of the
Photoelectric Effect

66
Do TWO of the following; then discuss
with your counselor the different kinds
of radiation and how they can be used:
a. Build an electroscope. Show how it works.
Place a radiation source inside and explain
the effect it causes.
b. Make a cloud chamber. Show how it can be
used to see the tracks caused by radiation.
Explain what is happening.
67
Electroscope
• An electroscope is a device that is used to
demonstrate properties of static electricity.
• The electroscope demonstrates the repulsive
force that is exerted between two nearby
objects with the same electric charge.
68
Cloud Chamber
• The cloud chamber, also known as the Wilson chamber,
is used for detecting particles of ionizing radiation.
• In its most basic form, a cloud chamber is a sealed
environment containing a supersaturated vapor of water
or alcohol.
• When an alpha or beta particle interacts with the
mixture, it ionizes it.
• The resulting ions act as condensation nuclei, around
which a mist will form (because the mixture is on the
point of condensation). The high energies of alpha and
beta particles mean that a trail is left, due to many ions
being produced along the path of the charged particle.
69

Part 5 Do ONE of the following; then
discuss with your counselor the principles
of radiation safety:
b. Describe how radon is detected in homes.
Discuss the steps taken for the long-term and
short-term test methods, tell how to interpret
the results, and explain when each type of test
should be used. Explain the health concern
related to radon gas and tell what steps can be
taken to reduce radon in buildings.
71
Radon
A Science Issue
72
What is Radon?
• Radon is an indoor air pollutant.
• Radon is a colorless, odorless radioactive
gas that comes from naturally occurring
uranium in the soil.
• The only way to tell how much radon a
home has is to TEST.
73
Surgeon General’s Warning
• “Indoor radon is the second-leading cause of
lung cancer in the United States and
breathing it over prolonged periods can
present a significant health risk to families all
over the country.”
74
Test!
• The only way to know the radon level in a
building is to test.
• Basement, crawl space, slab on grade or
foundation combinations can have a radon
problem.

Current Name
• Radon has been known by its current name
since 1923.
• It was named after the element radium.
The suffix “on” was used as with all other
inert gases.
77
Radon Action Level
• The USEPA set an action level for indoor radon concentration
of 4.0 picocuries of radon per liter of air (pCi/L).
• USEPA selected 4.0 pCi/L because of the technological and
economical bases.
• Risk at 4.0 pCi/L about seven (7) people out of a thousand
could get lung cancer.*

80
Radon Exposure
• Radon and Radon Decay Products
(RDPs) are breathed in and the Radon
is exhaled.
• Because they are solid particles, RDPs
remain in lung tissue and are trapped
in the bronchial epithelium and emit
alpha particles which strike individual
lung cells and may cause physical
and/or chemical damage to DNA.

How did radon originate in Ohio?
• Glaciers from Canada deposited uranium in
the soil.
• Radon results from the uranium deposits.

83
Radon can enter a house through
many paths.
84
Pressure Differentials and Radon Entry

Air pressure
differentials between
the building and
outside air causes
radon from the soil
to be drawn into the
house resulting in
elevated indoor
radon levels.
85
Common Entry Points
• Foundation Wall Joint
• Crawlspace
• Sump Pits
• Cracks in Floors
• Utility Penetrations
86
Who can test?
• The occupant of a dwelling may test their own
home. Test kits are available from hardware and
department stores or directly from laboratories
listed on the Ohio Department of Health Radon
• website http://www.radon.com/sub/oh/
87
Test the Footprint
•
Footprint means each foundation type in direct contact with
soil or other material.
•
Short-term or long-term measurements shall be made in
each lowest structural area suitable for occupancy. For
example, a split-level building with a basement, a slab-ongrade room and a room over crawlspace shall have
measurements made in each of the foundation types: the
basement, a slab-on-grade room and a room over the
crawlspace.
88
Detector Placement is Crucial
•
Place in an area where the detector will not be disturbed.
•
At least 3 feet from doors or windows to the outside.
•
Out of the direct flow of air from a ventilation duct.
•
At least 1 foot from exterior walls.
•
20 inches to 6 feet from the floor.
•
At least 4 inches away from other objects horizontally or vertically
above the detector.
•
At least 4 feet from heat, fireplaces and furnaces, out of direct
sunlight, etc.
89
Rooms to Test
• Measurements shall be made in rooms that
can be regularly occupied by individuals,
such as family rooms, living rooms, dens,
playrooms and bedrooms.
90
If Tests Are Above 4.0 pCi/L
• Ohio provides a list of Professional Radon
Mitigators trained to reduce radon levels.
• Professional Radon Mitigators and
Technicians must meet specific requirements
to obtain a license with Ohio.
91
Interpreting Radon Test Results
• The average indoor radon level is estimated to
be about 1.3 pCi/L; roughly 0.4 pCi/L of radon
is normally found in the outside air.
• A radon level below 4 pCi/L still poses a risk.
Consider fixing when the radon level is
between 2 and 4 pCi/L.
92
93
•
Mitigation Systems Reduce Radon
Collecting radon prior to by:
its entry into the building
and discharging it above
the highest eave.
• Modifying building
pressure differentials.
94
Active Soil Depressurization
•
Active Soil Depressurization uses a
fan to draw radon from beneath the
house.
•
All radon mitigation systems shall be
designed to reduce a radon
concentration in each area within
the footprint of the building as low
as reasonably achievable (ALARA).
•
Crawl spaces must be included in a
radon reduction plan.
