Abstract:
Human beings without their exhibited or exposed as natural sources of exposure, which include
cosmic rays, cosmogenic radionuclides and mainly radionuclides and mainly radionuclides. Radon 2,
specifically the 38U series decay product, has the highest2 is for dosimetry in watchful environments,
on average, with nearly 54% of the world's exposure derived from natural radioactivity. When
ingested and especially when inhaled, it may present a deterministic potential risk to living beings. In
the Brazilian Northeast, more precisely in the Seridó of Paraíba, there is a predominance of pegmatitic
geological formations, which contain occurrences of uranium and risk configuration due to the
emanation of 222Rn. In this context, this research objectively evaluates the radioactive risk resulting
from exposure to radon and exposure in indoor environments in the population in the eastern Seridó
of Paraíba, with a strong influence of the analysis on its local economy. Monitoring was performed
with the aid of passive dosimetry using an alpha detector, model Corentium Home. The experimental
arrangement for measuring floor variation was defined in indoor environments for prolonged stay in
places that have water points, bathroom and kitchen, always positioning the device at a floor height,
90 m < 1.50 m. Research has also been carried out in resource transport mines. At the same time, a
lemma defining parameters and habits that can be correlated with the research results was applied.
Descriptive statistical models were used for data processing and inference about the radiometrics of
the municipalities. ² They were found in ²R of the eastern Seridó of Paraíba, but at low levels. The
radioactive current from exposure to ²²²Rn in indoor environments in the population residing in Picuí
and Nova Palmeira ranged from 0.0 to 31.82 Bq/m³, being a prognosis of the average of raon gas and
its descendants five times lower than the maximum limit of 100 Bq/m³ stipulated by the WHO. It was
verified that the rooms that used water in their internal environment, bathroom and kitchen, were
verified in the ²²² R. The use of water in internal environments was identified as an indispensable
variable in the analysis of radionium 222 indoors. With good and positive water sources for water
sources, a strong presence of water was found, being a strong in the waters of Picuí-PB, being a new
Palmeiras de Picuí-PB. In the other sources found, the ² was not verified with. The dosimetry, for the
protection allowed for the study area at the background level, being less than the cancer limited to the
UNSCEAR background. per 1 million people residing in the area for one year, below the world
average of 170 to 230 per million people per year. With ²²²Rn in the air, it was possible to correlate
with soccer-only cancer. In the eastern Seridó of Paraíba, all radiometrics indicated loss of miners,
and this can be explained by the fact that they are miners and ventilated, without health risks.
