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

Abstract

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 0.2239 ± 0.0007 ppm, 0.0156 ± 0.0001 ppm, and 0.1811 ± 0.0006 ppm, respectively. Pb, Cd, and Cu in the blood were 0.0898 ± 0.0008 ppm, 0.0432 ± 0.0010 ppm, and 0.1729 ± 0.0004 ppm, respectively. The highest alpha particle emission rate was found to be in age interval from 23 y to 28 y in milk, while the highest alpha particle emission rate was found to be in the age interval from 35 y to 40 y Conclusions This study concludes that no statistical significance between Pb, Cd, Cu and Eα in milk and blood at level 0.01. The following order of bioavailability was found with heavy metals Cu < Pb < Cd.

Assessment of alpha emitters in urine for thyroid diseases patients by CR-39 technique

“…It is found that the alpha emission rate in females 0.07 mBq.cm -2 is higher than that in males 0.065 mBq.cm -2 .Many previous studies, such as ref, have confirmed this result. [11,14]. This may return to the fact that the total blood volume in females is usually lower than in males [15,16].…”

“…We need to calculate the efficiency of the CR-39 detector by determining two parameters. Then, using equation 1 to calculate the efficiency, [11] V B founded by equations 2 [10 ]. µm/s is the thickness of the layer removed from the detector's surface in µm , : time of etching process.…”

Detection of Radon Exhalation from Various Building Materials Using CR-39, RAD7, and Biosensors

“…The chemical solution has the ability to affect the damaged areas by alpha particles [18]. The chemical solution was prepared by dissolving 50 g of NaOH (6.25 N) in 200 ml of deionized water.…”
