The Science of Radiation Protection
Radiation• What do you think of when you
hear the terms:• Radiation• Atomic• Radioactivity• Nuclear
Brief History of Radiation Protection
Discovery of X RaysWilhelm Roentgen discovered x rays in November 1895 and announced his discovery on January 5, 1896. Scientists had been making x
rays without knowing it for years.
Medical uses of x rays began almost immediately thereafter.
Diagnostic x-ray images were taken within 2 weeks.
Radiation therapy for cancer performed within 6 weeks.
Bizarre claims were made•An x-ray image of a bone projected
onto the brain of a dog would make the dog salivate;
•X-ray baths supposedly cured blindness and criminality;
•Beauty parlors used x rays to remove unwanted hair;
•Leaded undergarments were sold to protect the modesty of girls.
Discovery of Radioactivity• While all of the excitement over x rays was
going on, Henri Becquerel discovered radioactivity in March 1896. Unlike x rays, radioactivity did not interest the public at first because it was not very plentiful.
• By 1903, Radium was commercially available• Cancer treatments were performed by August
1903 (Alexander Graham Bell first proposed this.) • Watch dials were painted with radium.• Public’s fascination with radioactivity began.
Bizarre uses of radioactive material• Drinking radium contaminated water was
considered healthy. • Liquid Sunshine (a drink which glowed when
mixed with radium) became popular.• Radium bearing medicines were patented. • A farmer advocated the addition of radium
to chicken feed to produce hard boiled eggs.

Radiation injuries occurred
•The first reported injury (eye irritation) was published on March 5, 1896.
•Skin burns, dermatitis, and alopecia were reported as early as April, 1896.
•The first report of radiation sickness occurred in November, 1896.
Obviously there was a need for radiation protection.

Benefits and Risks• It should be noted that there are
beneficial uses of radiation, from treating cancer to generating electricity, BUT it can be harmful if used in an unsafe way, exposing people to the potential harmful effects of radiation. For this reason both the states and federal government regulate the many uses of radiation.
Health Physics• The profession devoted to
protecting people and their environment from potential radiation hazards, while making beneficial uses of radiation and radioactivity possible.
Health Physicists• Scientists who control the
beneficial uses of ionizing radiation while protecting workers and the public from potential hazards.

Professional Certification
• For the professional health physicist, certification may be obtained from the American Board of Health Physics (ABHP)
• For health physics technicians, registration may be obtained from the National Registry of Radiation Protection Technologists (NRRPT).
You may seek certification at either of two educational and experience levels:
