These are only a few of the achievements of radiation chemistry, and they are becoming more impressive from day to day.
But radioactive radiations are not only man's friend. They are also his enemy. They are a subtle and merciless enemy, .causing radiation sickness.

   There are no universal remedies as yet for this grave disease. The best policy is to eliminate all possibility of exposure to radioactive radiations.

    But how? Lead blocks, concrete walls several metres thick, and heavy layers of metal and stone absorb these rays quite reliably. But this is very expensive, cumbersome and inconvenient. Imagine a man clothed in a lead suit. . .

    Chemists, where are you? Won't you be able to find a simpler means of protecting man reliably from irradiation?
The first experiments in this line (only experiments so far) have already been made.

    X-rays expose photographic plates and films instantly. They break down the light-sensitive layers of the silver bromide emulsion.

    Now here is what some Italian chemists did about four years ago. They moistened the surface of a photographic plate with a solution of the inorganic compounds - titanium sulphate and selenious acid. 

    The plate became insensitive not only to visible light, but to X-rays as well.
