- 1 If a large body like a human being can be affected by his little radiation as an x-ray what happens to small bacteria and viruses and other pathogens in the human body when they get hit by radiation then you take and activate please elaborate because play to the boils and radiation sickness has similarities

Let's build on the radiation connection there's a coincidence here we had high levels of radiation in the 1970s when we had a problem and we had a lot of chemicals in the air with the Spanish flu in the early 1900s there was the Hong Kong flu there was all that nuclear testing there's a coincidental tie here that's beyond coincidence with the object of influenza encephalitis the electromagnetic fields the radio waves and radiation from outside of our atmosphere 2017 this planet I hit by a gamma ray burst and there was excessive radiation in the planet from Japan and Chernobyl

Look a little deeper on the radiation connection because it's a common thread there's been excessive radiation and chemicals in the air both times bad air bad water bad food and that my immune system gets mutated in some way because of radiation that could be the reason why. The mutation from the radiation the body is doing is what's allowing these various viruses and everything to kick up that's the beyond coincidence

Does radiation exposure change immune responses to flu in humans?
The short version: the honest answer is that nobody has cleanly measured this in people, and the animal data point in both directions.
The question is narrow: does radiation exposure change how a human immune system handles flu? Nothing in front of me tests that directly. What exists is animal work on radiation and immune function, and it cuts both ways. In mice, a single low whole-body X-ray dose raised natural killer cell killing from about 7% to about 11% and macrophage killing from about 29% to about 42% [1]. Ten daily low doses did the same in two mouse strains and reduced lung tumor colonies [3]. But the same paper found the effect faded within days of stopping exposure [3], and irradiating the cells directly in a dish did nothing at all [1]. The boost came from the whole animal, not the cells.
At high doses the picture flips. Lethal whole-body irradiation let tumors grow in the lungs of mice that normally clear them [2], and depleting T cells did the same thing [2]. Bone marrow transplant conditioning at 12 Gy left T cell and myeloid populations roughly intact across radiation types [4], but that is a reconstituted system, not a normal immune response to a virus.
| Exposure | Model | Immune effect |
|---|---|---|
| 0.1–0.2 Gy, single dose | Mouse | NK killing up, macrophage killing up [1] |
| 0.01–0.1 Gy, ten daily doses | Mouse | Same boost, fades after exposure stops [3] |
| 0.1–0.2 Gy, cells in dish | Mouse cells | No effect [1] |
| 18 Gy whole body | Mouse | Tumors grow that were previously cleared [2] |
None of this is influenza. No record here measures flu infection, flu severity, or antibody response after radiation in people or animals. The dose matters enormously, and human environmental exposures like Chernobyl or background radiation are not the same as these lab doses.
My call: the evidence does not establish that radiation changes human flu immunity either way, and the mouse data suggest low doses may briefly stimulate some immune cells while high doses suppress them. Confidence: low.

Immunological Mechanism of the Low-Dose Radiation-Induced Suppression of Cancer Metastases in a Mouse Model
Low-dose whole-body X-ray exposure (0.1–0.2 Gy) suppresses L1 sarcoma lung metastases in BALB/c mice and stimulates NK-cell and macrophage anti-tumor functions, while in vitro irradiation alone does not.

Strain-Specific Susceptibility for Pulmonary Metastasis of Sarcoma 180 Cells in Inbred Mice
Intravenous S180-Fluc cells produce strain-dependent pulmonary metastasis in inbred mice; BTBRT+tf/J mice clear tumors, and irradiation or T-cell depletion enables pulmonary tumor growth.

Effect of Low Doses of Low-Let Radiation on the Innate Anti-Tumor Reactions in Radioresistant and Radiosensitive Mice
Ten daily low-dose X-ray exposures stimulated NK-cell and macrophage anti-tumor functions and reduced pulmonary tumor colonies in both BALB/c and C57BL/6 mice, with strain differences in kinetics and dose dependence.

Cesium-137 and X-Ray Irradiation Yield Comparable Immune Phenotypes and Activation States in Bone Marrow Chimeric Studies
Cesium-137 and 225/320 KVp X-ray irradiation produced comparable survival, donor chimerism, immune lineage distribution, and activation states in bone marrow chimeras across multiple organs, supporting X-ray replacement.
