The concentration of naturally occurring
radionuclides in sustenance is changed generally due
to contrasting foundation levels, atmosphere, and
agricultural conditions that prevail. The largest
contribution to the inhalation exposure comes from
the short half-life decay products of radon (222Rn) [1].
The 222Rn is a naturally occurring colorless, odorless,
tasteless inert gas, which is indistinct to the human s
sense. It is delivered persistently from the rot of
normally happening radionuclides, such as Uranium-
238 (238U), Uranium-235(235U), and Thorium-
232(232Th). Uranium is a naturally occurring
component present in practically all minerals, sand,
vegetables, and soil. The isotope of 222Rn, delivered
from the decay of 238U, is the principal source (roughly
55%) of inside radiation presentation to human life [2,
3]. Radon gas escapes easily from the ground into the
air and disintegrates through short-lived decay
products called radon daughter or radon progeny. It
has a half-life of 3.82 days and decays by alpha
ejection, and the alphas energy is 5.5 MeV [1-4]. There
are a few essential pathways for the transfer of
radionuclides to eating routine of people. The mainly
ways of radon to causes the dose through food, water
and medicine. Due to their quality in soil and
phosphate composts, primordial radionuclides and
their progeny are transferred by the food chain to the
human body [5]. It is important to measure the
radionuclide substance of food and water samples to
evaluate potential radiation doses and assess the
consumers exposed to radiation. The most imperative
and overwhelming supporters of the inward breathing
portion are the decay results of radon. Radon and its
decay items that are noticeable all around structure
the primary common sources of irradiation in human.
Radon concentrations are higher indoors, yet there is
also a considerable focus outside. Other than
influencing general society, it is in charge of numerous
malignant growths passing among uranium diggers
[1]. The estimations of natural radioactivity in
ecological components have been conducted in
various nations to build up standard information from
the natural radiation levels [3-9]. The objective of this
study was to measure the radon concentrations in the
milk and tea samples collected from Misan markets in
Iraq.
