Findings

1. Heller's own publication: Nature 183:905-906 (1959) [web]

J. H. Heller and A. A. Teixeira-Pinto (New England Institute for Medical Research), "A New Physical Method of creating Chromosomal Aberrations" (doi:10.1038/183905a0; PubMed record exists). - Method: a pulsed radio-frequency source at 27 Mc/s, chosen "In order to minimize dielectric heating"; pulses of the order of 5 x 10^-6 s (OCR "5 x 10-s"; exponent not certain); most effects with 80 to 180 pulses per second; electrodes with an air gap; garlic root-tips in water between insulated electrodes; "No temperature increase in the water was noted"; 5-minute exposure, examined 24 h later. - Reported effects: linear shortening of chromosomes, pseudochiasmata, amitotic division, bridging and other irregularities, which "mimicked those produced by ionizing radiation and c-mitotic substances". - Heller's claim of specificity: the effect is a tool that "may induce chromosomal aberrations to a degree contingent upon frequency, pulse, power, exposure time, and the axis of the cell vis-a-vis the field". - No numbers of cells, controls or statistics are given in the letter (it is a one-page letter with a figure); the temperature statement is qualitative. Bearing: Heller's patent US 3,095,359 (run 2) cites Kassner's US 2,089,966. This letter is the published experimental claim behind it. It is a second, independent claimant of frequency-dependent, non-heating biological effects (claims 1-3), not a test of Kassner's own examples.

2. A US Navy contractor survey (1960) summarised Heller's work as non-thermal and frequency/species specific [web]

Midwest Research Institute (Kansas City), "Survey of Radio Frequency Radiation Hazards", Summary Report, 20 May 1959 to 19 May 1960, Navy Bureau of Ships contract NObs-77142, by P. C. Constant Jr. et al., 14 June 1960 (MRI Project 2307-E). Read from the text extract: - On Heller's unicellular work (p.147): at about 5 Mc the organisms move "parallel to the electrodes, or perpendicular to the electric field", at 20 Mc parallel to the field, and at intermediate frequencies they are unaffected, fixed, or spin; "These experiments must be performed at low power levels to insure that heating is negligible"; Heller used a 1-100 Mc generator, 0-20 kV, pulses 1-20 microseconds at 30 to 10,000 per second; "These phenomena are frequency and species specific"; fields "quite high (300-1,200 v/cm); however, the total power requirements are quite small"; Heller is "able, apparently by selective polarization, to pull amoebas apart by using the proper frequencies and pulse rates". Source cited: Heller, "The Effect of Electromagnetic Fields on Unicellular Organisms", 12th Annual Conference on Electrical Techniques in Medicine and Biology, Philadelphia, Nov 1959. - On chromosomes (p.148): r-f between 5 and 25 Mc "has been shown by Heller to cause chromosome aberrations"; "The effect seen, however, is not a thermal one. A new specific nonthermal effect has apparently been found." - On growth (p.148-149): "In the 1 to 20 meter band, however, growth of many organisms is enhanced. The reaction is not because of heating; rather, it appears to be a direct effect of the electric field. Further, frequency specificity is seen." (citing Army Chemical Corps work and Susskind, Vogelhut). - Appendix E (pp.114-116), pearl-chain formation: first reported by Muth (Kolloid-Z. 41, 97, 1927), theory by Krasny-Ergen (Hochfrequenztechnik und Elektroakustik 48, 126, 1936; 49, 195, 1937); also Liebesny (Arch. Phys. Therapy 10, 736, 1939) and Schwan. The mechanism is induced polarisation of particles whose dielectric constant differs from the fluid; chains form when the alignment energy exceeds the thermal energy kT. "Irrespective of the theoretical basis for the phenomenon, the fact remains that pearl-chain formation is a reality." In living tissue it "has not yet been observed". Elsewhere (p.146) the report calls pearl chains not recent and not "demonstrated to have any clinical significance", with body temperature (high kT) working against chain formation. - The authors' stance: they treat these as hazards to be studied; they do not report their own tests of Heller's effects. How this bears on the claims: it is a 1960 government-contract assessment (an interested party in the sense of the prompt: the Navy's RAD HAZ programme, whose stake is in setting exposure standards) that took frequency-specific non-thermal effects seriously. It is reporting, not replication. It also records the mainstream physical mechanism (Maxwell-Wagner interfacial polarisation; Schwan and Shen) offered for Heller's orientation effects: a frequency-dependent dielectric response of layered particles, which is frequency-dependent but broad, not a molecular "natural frequency" in Kassner's sense.

3. A later negative test in a different organism [web]

S. Mittler, "Failure of 2- and 10-meter radio waves to induce genetic damage in Drosophila melanogaster", Environmental Research 11(3):326-330, June 1976 (PMID 820551, doi:10.1016/0013-9351(76)90094-3). PubMed has no abstract; the full text is behind ScienceDirect (CAPTCHA). The title states a negative result at 30 and 150 MHz (10 m and 2 m). Fruit flies, not garlic root tips, so it is not a direct replication of Heller's 27 Mc root-tip result. Google also shows Heller's letter cited in later work (e.g. Mayers 1970 on microwave fixation; Zaret 1988 in JAMA). Whether anyone repeated the garlic root-tip experiment is not yet known.
