HISTORY

Radioactivity was discovered in 1896 by Henri Becquerel and Pierre and Marie Curie, who confirmed its existence by isolating several other radioactive elements, including radium.

Radioactivity has two origins:

Natural, due to the instability of the isotopes of certain elements in the periodic table.
Artificial, obtained by bombarding stable elements with beams of particles that render them unstable.

A) Earth radiation - B) Cosmic radiation - C) Radon - D) Industry and other sources - E) Medical examinations and treatments

TYPE OF EXPOSURE AND DOSE

Exposure to ionizing radiation can take many forms:

During a medical or dental X-ray
During air travel
Natural radioactivity (in New Caledonia, the main natural source is Radon).

Today, we consider 2 families of effects:

Deterministic effect: These are early effects that always appear (a few hours or days) after a threshold dose. Their severity is proportional to the dose received, and can be punctual or irreversible.
Stochastic or random effects: These are delayed, slow-onset, random effects.

RADIATION PROTECTION

Radiation protection aims to prevent deterministic effects and minimize stochastic effects. That's why INTERMED works in close collaboration with supplier VARAY LABORIX, to meet the specific and increasingly sophisticated needs of radiology professionals. We offer a wide range of products, from individual or collective PPE to radiation protection for your premises.
