VII. Render from English into Ukrainian.

In 1898 the Curies obtained a new element whose radioactivity was several million times stronger than that of uranium.

They named this new substance "radium". Radium is very expensive, as it is extremely rare. Several tons' of rich ore are required in order to obtain one ounce of radium worth many thousands of dollars.

Radium possesses many interesting properties. It liberates heat, electrifies the air; it causes many substances to become phosphorescent when brought near it; it kills bacteria and other tiny organisms. Radium is used for medical purposes, as it helps to locate and diagnose different growths. There are many other applications of radium and more are developing each year.

1. We are steadily finding new means of protection from radiation. He always says what he means. The word "safe" means "free from danger".

2. Radiation can produce bums and injuries of various kinds. People should be very kind to animals.

3. This clock doesn't show the time: the hour hand is missing. We pull back our hands from a flame or a very hot objects. On the one hand this research is very promising but on the other hand it is expensive and time- consuming.

AUTOMATIC PLANTS IN INDUSTRY.

Here are some facts about a new automatic plant in Kyiv. The new plant is truly an enterprise of tomorrow – a factory where men and women are free from manual labour, where machines do all the hard work.

In the high, light and clean halls hundreds of mechanical devices act with unprecedented precision and timing. The machine assembly transforms metal into complex machine parts without human intervention.

A few people walk quietly round the machines and check their oper­ation. These are operators. They operate separate machines. They keep them working at just the right speed. Every operator is a very skilled technician with a wide knowledge of machines. He knows machines so well that he can feel the pulse of each machine. If any trouble arises, the operator determines the damage and repairs it quickly, in seconds. He changes tools and starts the device again. But to repair damage is only a Part of his job. To prevent stoppages is even much more important.

The operators are well trained people. A controller sits at a desk. He merely watches the illuminated glass panel on which he sees the entire machine assembly in graphic form. As he knows the connection between the various working processes, he directs various sections and shops of the plant.

Machines are used not only to produce high-precision parts. They inspect the quality of work. If any stoppage takes place an automatic device immediately sends a signal. At every stage of its journey through the plant, the part goes through accurate mechanical inspection. A mechanical device inspects and checks the weight of the part, precision of its diameter, solidity of metal. Another mechanical inspector not only checks the precision of the complex parts but sorts them out in different sizes.

The plant of today is a factory which looks more like a first-class laboratory than a plant.
