Fabrication of biosensor for the assessment of radon and lead levels in the blood.

This study aimed to develop and test a biosensor for detecting radioactive radon gas and lead ions in blood samples collected from donors in Iraq. The biosensor was made up of aptamer, acetic acid, malachite green, and TRIS-HAC, and results were measured using a fluorescence spectrophotometer. This study found that Rn in the blood varied between individuals, with higher levels in males and smokers, and the highest concentration found in a male patient with cancer.

Alpha particle rates and heavy metal concentrations in cosmetics available in the Najaf markets.

This study focuses to measure the emission of alpha particle rates (EAPR) and heavy metal concentrations (Cd, Pb, Zn, Cr, and Co) (HMC) in some cosmetics (kohl eye, compact powder, and lipsticks) from Najaf markets using CR39 Detectors and Spectrophotometry, respectively. The EAPR range from 0.0068 to 0.

Relationship between heavy metals and alpha emission rates in breast milk and blood of women.

Background: The current study determines the relationship between heavy metals and alpha particles emission rates in milk and blood of lactating women in Diwanyah, Iraq.

Methods: Heavy metals and alpha particle emission rates have been measured using an Atomic Absorption Spectrophotometer and a Nuclear Track Detector.

Results: The results show that Pb, Cd, and Cu in milk are 0.

Relationship between heavy metals and alpha particles as a marker of environmental pollution in rice consumed in Najaf, Iraq.

This study focuses on the emission of alpha particle rates (EAPR) and heavy metal concentrations (HMC) in the rice from Najaf markets. Nuclear Track Detectors and Flame Atomic Absorption Spectrophotometry, were used respectively. This study shows the pollution in the environment through AP and HM and also finds the relationship between AP and HM.

Radiobiological long-term accumulation of environmental alpha radioactivity in extracted human teeth and animal bones in Malaysia.

In this study, the radiobiological analysis of natural alpha emitters in extracted human teeth and animal bones from Malaysia was estimated. The microdistributions of alpha particles in tooth and bone samples were measured using CR-39 alpha-particle track detectors. The lowest and highest alpha emission rates in teeth in the Kedah and Perak states were 0.
