After the measurement process is completed, information about the nitrate content in the product will be displayed.
"Normal nitrate content. The product is safe for consumption.
"Insignificant excess of standard". Product can be consumed in small quantity. Heat processing is
recommended. It is not recommended for children and the elderly to consume the product.
"Significant excess of standard". It is recommended not to consume the product.
ATTENTION! There are fruit and vegetables in the list of Nitrate tester, which contain
air cavities (for instance, sweet pepper). When measuring such products, it is
important not to insert the probe into the air cavity. When the probe is inserted into the air
cavity, the measurement result will be misleading.
Radiation measurement – Dosimeter
Some chemical elements (so called radioactive isotopes) contain unstable nucleus that decay into small elementary particles or
quanta. Detachment of elementary particles or quanta is called radiation.
Radiation is ionizing, because it leads to atomic ionization of substance that is struck by radiation. Ionization is called the process of
striking one or a few electrons out of atom. After that, nucleus and left electrons create a system that is positively charged and is
called an ion.
Ionized atoms strongly differ from average nucleus. Ions destroy other molecules by breaking a bond between nucleuses. That is the
reason why ionized radiation influence on human’s health is harmful.
Radiation influence on the human body is called irradiation. Irradiation transpierces any body tissues and ionizes their particles and
molecules. This leads to creation of ionized nucleuses (ions or so-called free radicals) that destroy molecules and lead to inclusive
death of tissue cells.
As it was said before, nuclear disintegration into elementary particles is accompanied by radiation of these particles. This
radiation is divided into following types:
