Abstract

The main aim of this study was to determine the bioaccumulation of 210Po in the hair of various cat breeds and an attempt to interpret whether the following factors, such as: breed, length of hair, gender, age, place of living or residence, weight, type of food consumed, taking medications, origin taking into account the structural division of Poland into voivodeships and physiological processes such as pregnancy and lactation have a significant influence on the concentration of this radionuclide. The obtained results show that the factors such as breed, length of hair, living of the cat in a given voivodeship and the type of food served influence the degree of 210Po bioaccumulation.

Highlights

Ionizing radiation is widely present on Earth

Summary

Introduction

Ionizing radiation is widely present on Earth. The average annual effective dose from natural sources in Poland equals 2.43 mSv. 49.4% of the background dose is derived from the radioactive gas radon, 19.1% from gamma rays and 31.5% from other sources such as cosmic rays and in-body radionuclides [7]. 210Po is an interesting radioactive element due to its high radiotoxic properties. Polonium and radon are two natural radioactive materials delivering the highest natural dose to organisms [14]. There are many sources of 210Po in the atmosphere, but releasing from the surface 222Rn formed from 226Ra, is the main one. Another source of polonium is precipitation such as rain, snow, and atmospheric dust [22]. Natural radiation brings many advantages in different life areas. It is used in biology, astronomy, food preservation and medicine for diagnosis, treatment, and research [15]. Radiation and radioisotopes may cause damages to different organisms,
