Conducting the study: National Toxicology Program (NTP) within the National Institute of Health of the US Government (Sponsoring US$ 25 million)
Date: 23 June 2016
Information: n=1260 animals (rats). The animals were irradiated for up to 106 weeks with up to 900 megahertz (lower mobile radio standard).
Findings: The findings of the study show that mobile phone radiation can lead to tumours. To be more precise, two types of cancer (schwannoma, glioma) and pre-cancerous cell changes (hyperplasia of glial cells) were documented in a number of rats (46 heart and brain tumours among 540 irradiated male rats; female rats = no tumours). These findings corroborate the appraisal by the IARC (International Agency for Research on Cancer) that mobile phone radiation is potentially carcinogenic.
Tumour Promotion through High-Frequency Electromagnetic Fields in Combination with Carcinogens
Authors: Klose, M; based on the research of Tillmann and Lerchl et al (2010)
Conducting the study: German Federal Office for Radiation Protection (BfS)
Date: March 2015
This study involving experiments on animals investigated whether high-frequency electromagnetic fields of the mobile radio standard UMTS (1.97 GHz) can promote the development and growth of tumors without itself causing the formation of tumors. A pilot study by Tillmann et al. (2010) reported the tumor-promoting effects of high-frequency electromagnetic fields. These indications should be investigated.
For the most part, the findings of the pilot study were able to be confirmed and expanded. In both studies, the number of tumors (carcinomas and adenomas) in the liver and lung have risen in the combination groups as a result of mobile phone radiation.
