Scientists: to create a radiation dosimeter enough foil and yeast

U.S. experts interested in the possibility of a simple and compact sensor fixing ionizing radiation. It was quite likely.

Учёные: Чтобы создать радиационный дозиметр - достаточно фольги и дрожжей

As reported by scientists, in order to create a radiation dosimeter fairly common improvised. They did it using paper, foil and yeast.

When the sensor is applied to water, yeast start the fermentation process of glucose and the release of carbon dioxide. He then changes the conductivity of the sensor.

Inside the instrument, the yeast is surrounded by the adhesive mass. It is attached to the foil with the contacts for measurements. The outer loop is used paper.

The process of change of conductivity with increasing of radiation background is only a few minutes, and then you get the result.

Some disadvantage of this dosimeter are temperature limitations on its use. In particular, when three degrees of heat the yeast just “are”, but when sixty die. The optimal temperature of plus twenty-one degrees. The minimum dose that is able to detect the device – 1 mrad.

This is an essential tool for radiologists and other people working constantly in the area of excessive exposure. In the case of a technical error, they are at risk to her overdose.

In order to control it now using the expensive dosimeters or passive sensors, the readings of which are read only a few weeks when it may be too late.

New cheap device can be a perfect outlet.
