Control group #2

Human peripheral blood lymphocytes were isolated from a healthy 60 years old male donor by differential centrifugation on Histopaque (Sigma-Aldrich Chemicals ltd.) from 30 ml of whole blood obtained via venipuncture of v.cubitale into vacutainers containing anticoagulant (K2), and maintained in RPMI 1640 nutrient with antibiotics and antimycotics.. Four standardized samples of the culture were placed in 2ml phials sealed with a plastic cap and pre-sterilised at 121degrees C under pressure. There was about 0.5 of culture in each sample. All glassware and instruments were handled in a purified air laminar flow unit to avoid bacterial contamination.

This control group describes the number of lymphocytes after the vials containing this blood sample have been irradiated for 8 hours with a standard mobile phone (Philips C12). The mobile phone was only in stand-by mode! All tests were carried out in an air laminar flow unit for genetic engineering and microbiological work with cell cultures.

The analysis of ten series of tests showed am average number of:

> 46 viable lymphocytes (grey columns)
> 6 non-viable lymphocytes (red columns)

* * *

This test series clearly shows that mobile phone radiation (only stand-by) destroyed almost 50% of all lymphocytes in eight hours!

Once again: Lymphocytes are the defence cells of the human body.
