When one studies strongly radioactive substances special precautions must be taken. Dust, the air of the room, and one's clothes, all become radioactive.

When one studies strongly radioactive substances special precautions must be taken if one wishes to be able to take delicate measurements. The various objects used in a chemical laboratory and those used in a chemical laboratory, and those which serve for experiments in physics, become radioactive in a short time and act upon photographic plates through black paper. Dust, the air of the room, and one's clothes all become radioactive.

Scientist believe in things, not in person

Radium is not to enrich any one. It is an element; it is for all people.

Stability can only be attained by inactive matter.

We must not forget that when radium was discovered no one knew that it would prove useful in hospitals.

I am among those who think that science has great beauty.
