Summary
Radiation exposure from Three Mile Island accident particulates, primarily Strontium 89, caused severe immunosuppression and increased cancer rates. This study identifies an unrecognized exposure mechanism following nuclear accidents.
Area of Science:
- Nuclear Chemistry and Toxicology
- Radiation Biology
- Environmental Health
Background:
- Anecdotal reports of injuries post-nuclear accidents contrast with failed studies linking cancer rates to radioactive releases.
- A significant dose of at least 0.5 Sieverts is often indicated by observed injuries.
Purpose of the Study:
- To resolve the dissonance between anecdotal injury reports and epidemiological study findings after nuclear accidents.
- To identify an unrecognized exposure mechanism and its associated health effects from the Three Mile Island accident.
Main Methods:
- Analysis of knowledge regarding reactor releases and health effects from the Three Mile Island accident.
- Inference of a relationship between inhaled particulates and severe immunosuppression.
- Hypothesis formulation: Strontium 89 particulates caused observed health effects.
Main Results:
- Strontium 89 comprised over 90% of particulates, acting as point sources of chronic beta irradiation.
- Individuals beneath the plumes exhibited an abrupt rise in "Deaths from all Causes" consistent with severe immunosuppression.
- Observed excess cancers aligned with expected outcomes from doses of 0.5 Sieverts or more.
Conclusions:
- The hypothesis is validated, confirming Strontium 89 particulates as the cause of observed health effects post-Three Mile Island accident.
- This study reveals previously unknown mechanisms and effects of low LET beta irradiation from particulates.

Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The nucleus of an atom is composed of protons and, except for hydrogen, neutrons. The number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element.

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

20.7K
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed...

02:50Nuclear Fission
12.5K
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large...

The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

02:33Initiation of Translation
39.1K
Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...
