Just how "Rad" is it?

How Detrimental is Radiation to Our Health? In what ways does Radiation Affect us?

Terms to Know

Radiation: "the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization"

Rem: (not just a band): a unit of radiation dosage as it affects humans

Chernobyl: A nuclear meltdown in Russia (Ukraine now) that leaked mass doses of radiation to the nearby population

Radiation at Different Levels

How is Radiation Measured?

-Different systems of radiation

-Typically measured in "rem" or "sievert"

Effects of Radiation at Different Rem

  • 0-5: safe; no observable impacts
  • 5-10: no observable impacts
  • 10-50: slightly increased cancer risk, blood cell decreases (with quick exposure), if locally exposed in the face, eye cataracts
  • 100-200: nausea, fatigue, significantly higher cancer risk, skin reddening like a sunburn
  • 200-300: nausea, vomiting within 24-48 hours, seek medical attention
  • 300-500: diarrhea within hours, hair loss, appetite loss within the week, medical attention required for survival, 1/2 exposed die without prompt medical attention
  • 500-1,200: death within days, breakdown of intestinal lining, internal bleeding
  • >10,000: death within hours

We are Constantly Exposed to Radiation

Radiation Dosing Chart

See how much radiation is given off my common things

Why Aren't we all getting Sick?

Everyone all around the world is continuously being exposed to tiny doses of radiation. These doses are (typically) so minuscule that we don't notice any effects

Medical procedures produce 96% of man- made radiation exposure

The Other 4%

Other Cases of Radiation from Non-medical sources


Saturday, April 26th 1986 at 1:15am


A nuclear reactor had a meltdown, exposing high doses of radiation to the surround biota, including workers and nearby communities

"Chernobyl cleanup workers had significantly increased risk of leukemia"

It's Not all Bad

Radiation can be useful in medical treatments including acting as an expedient to cancer cell depletion

Radiation Therapy

  • used to fight cancer
  • usually has "tolerable" effects
  • adverse effects are typically limited to site of treatment
  • highly effective and targeted
Demographic: Age and Risk of Thyroid Cancer in Russia

-<18: 58-fold increase ->64: 2.6-fold increase

short term

ARS- high dose penetrating internal organs
nausea, vomiting, headache, diarrhea
start within minutes
after symptoms alleived, person gets worse again
loss of appetite, bone marrow issues,fatigue, fever, skin damage: swelling itchiness, redness
treatment: reduce and treat infection, maintaining hydration, treat burns and injuries, bone marrow treatments
bone marrow destruction= CoD for most ARS patients

CRI-certain types of radiation
itchiness, tingling, erythema (skin redness) swelling (edema), other symptoms depending on the case
seek medical attention- while waiting, gently rinse with water- keep clean, dry, covered until proper treatment

What NY Times Says to Do

Call for emergency medical help or take the person to nearest emergency medical facility if you can do so safely

For Help

Any local hospital will have treatment for radiation

Nearby: Albany Med, St. Rose, Samaritan

To Conclude

Radiation can be extremely detrimental to our health, though small doses have little to no effect

It targets cells and targeted tissue, and can lead to cancer, ARS, CRI, and more

However, it can be useful in medical procedures and cancer treatment
