The Number of MPN/100ml decreases only 1% with 2 hours ELF-EMF exposure as shown in Fig (3).

In this issue, Gang Chen of the Department of Pediatrics and Human Development at Michigan State University and colleagues used an experimental model developed to test cancer-promoting chemicals to examine whether ELF-EMFs might play a role in cancer promotion [EHP 108:967-972].
ELF-EMFs are too weak to kill cells or (most scientists agree) to cause mutations and thus initiate cancer.
What the group was testing was whether ELF-EMFs could prevent differentiation in cells that had started down the road to cancer.
While the study showed that ELF-EMFs could conceivably play a biological role in carcinogenesis, cancer-promoting chemicals require a long exposure to promote cancer, and human exposures to ELF-EMFs are hard to gauge.
If ELF-EMF contributes to cancer, then it is important to determine the stage or stages of carcinogenesis that it affects.
Assuming that ELF-EMF plays a role in the carcinogenic process but that it is not a carcinogenic initiator, it follows that ELF-EMF is likely to be involved in the promotional phase of cancer.
Our results support the hypothesis that ELF-EMF acts as a tumor-promoting agent in mimicking the tumor promoter TPA by inhibiting DMSO and HMBA-induced Friend erythroleukemia cell differentiation and by stimulating cell proliferation.
9 m from the incubator to minimize the ELF-EMF exposure from the incubator to less than the background levels.
