12. LAW OF BERGONIÉ AND TRIBONDEAU
24th JAN 2021/HISTORY
Guillaume Vogin/2020
1. The law of Bergonie and
Tribondeau is that the
radiosensitivity of a biological
tissue is directly proportional to
the mitotic activity and inversely
proportional to the degree of
differentiation of its cells.
2. This law underpins the field of
radiation-oncology, although such
a general law may not apply
precisely in all cases.
3. 1906: Law of Bergonie’ and
Tribondeau
4. Although it is still popular and
taken as one of the founding laws
of radiation oncology, it was early
considered as a 'first
approximation
13. LAW OF FRACTIONATION- REGAUD
25th JAN 2021/HISTORY
Guillaume Vogin/2020
1. In 1906, Regaud discovered that one of
the effects of X-ray treatment is sterility.
He deduced that X-rays could also be
used against rapidly growing cells other
than gametes and, thus, against
cancerous tumors.
2. Regaud studied spermatogenesis and
radiotherapy in multiple animals in the
first third of the 20th century. Some of his
work assisted with Bergongie and
Tribodeau's formulation of their law in
1906. In 1927 Regaud published his data
on ram testis radiotherapy. In summary,
he found that
3. Sterilisation of a ram testis without acute
skin reaction was only possible with
fracitionated treatment (3 treatments 15
days apart)
14. TIME ,DOSE FACTOR CONCEPT- HENRI COUTARD
26th JAN 2021/HISTORY
1. Henri Coutard was a French pioneer in
radiation oncology and is credited with
establishing radiotherapy as a clinical
discipline. He performed early work on
the therapeutic use of Radium
emanation.
2. Coutard did laboratory work and
described elementary radio-physiologic
reactions
3. This was referred to as 'simple
fractionation', the delivery of small doses
with high dose rate.
4. As Coutard's results led to the
abandonment of single dose
radiotherapy, many hospitals preferred
the small dose/high dose rate method
over the less economical low dose rate
treatments

Theodore T. Puck /J Exp Med. 1957
1. Professor Eddie Barendsen, also
known as “Mr. Linear Quadratic
Model
2. Many radiobiological models
came and went, and it took
Barendsen more than 20 years
to publish what became known
as the linear quadratic (LQ)
model. In its original version
3. Barendsen preferred to use a1
and a2 instead of a and b
because “it is a mathematical
model” and not an ancient
language
24. 1. Marie and Pierre Curie, Polish and French chemists, discovered radium in 1898, according
to New World Encyclopedia.
2. The discovery came from the study of pitchblende (a type of uranium ore) found in
Bohemia (today's Czech Republic). The uranium was removed from the ore and the
remains were found to still be radioactive.
3. According to Peter van der Krogt, a Dutch historian, the element was named for the Latin
word "radius" or "ray" because the radiation emitted from the new element was about 3
million times greater than the radiation from uranium.
4. The Curies were able to extract about 1 milligram of radium from nearly 10 tons of
pitchblende, according to the Royal Society of Chemistry
5. Radium is a highly radioactive element and can be extremely dangerous. However, it was
once used in many everyday products, including wristwatches and toothpaste, and
thought to have curative properties until its intense radioactivity was found to cause
adverse health effects
6. The 1938 Food Drug and Cosmetic Act outlawed deceptive packaging that made Radithor
and other radium-branded products marketable. Bye-bye Radium Brand Creamery Butter.
7. Most of the radium comes from uranium mines in Democratic Republic of Congo
and Canada

31. FIRST PROTON CENTRE IN WORLD
12th FEB 2021/HISTORY
WIKI
1. The first suggestion that energetic protons could be an
effective treatment method was made by Robert R.
Wilson in a paper published in 1946 while he was
involved in the design of the Harvard Cyclotron
Laboratory
2. The first treatments were performed with particle
accelerators built for physics research, notably Berkeley
Radiation Laboratory in 1954 and at Uppsala in Sweden
in 1957.
3. In 1961, a collaboration began between HCL and
the Massachusetts General Hospital to pursue proton.
4. Over the next 41 years, this program refined and
expanded these techniques while treating 9,116
patients[ before the cyclotron was shut down in 2002.
5. The ITEP center in Moscow, which began treating patients
in 1969, is the oldest proton center still in operation.
6. The Paul Scherrer Institute in Switzerland was the
world’s first proton center to treat ocular tumors beginning
in 1984.
7. In addition, they invented pencil beam scanning in 1996,
which is now the state-of-the art form of proton therapy.
8. The world's first hospital-based proton therapy center was
a low energy cyclotron centre for ocular tumours at the
Clatterbridge Centre for Oncology in the UK, opened in
1989, followed in 1990 at the Loma Linda University
Medical Center Loma Linda, California

linear accelerator at Fermilab have the
highest energies available in the US and
among the highest in the world.
2. Fast neutron therapy utilizes high
energy neutrons typically between 50 and
70 MeV to treat cancer. Most fast neutron
therapy beams are produced by reactors,
cyclotrons (d+Be) and linear accelerators.
3. Neutron therapy is currently available in
Germany, Russia, South Africa and the United
States. In the United States, three treatment
centers are operational in Seattle,
Washington, Detroit, Michigan and Batavia,
Illinois.
4. The Detroit and Seattle centers use a
cyclotron which produces a proton beam
impinging upon a beryllium target; the Batavia
center at Fermilab uses a proton linear
accelerator.
