Old REM gauge
1 millisievert = .1 rems
2,000 millisieverts = 200 rems
New Sievert gauge
100 counts/minute = 1 microsievert
1,000,000 microsieverts = 1,000 millisieverts = 1 sievert
500 millisieverts / 1/2svh:
No visible effects.
750 to 1,000 millisieverts / ~1svh:
Brief periods of nausea on the day of exposure in about 10% of a group.
2,000 millisieverts / 2svh:
As many as 50% of a group may experience some of the symptoms of radiation sickness. Although only 5% to 10% may require medical attention, no deaths
4,500 millisieverts / 4.5svh:
Serious radiation sickness in most members of a group followed by death to about 50% in two to four weeks.
6,000 millisieverts / 6svh:
Serious radiation sickness in all members of a group followed by death of almost all members within one to three weeks.
1,000 millisieverts/hour is a recent radiation measurement reported outside reactor #3.
Rarely discussed in the media is ionizing radiation damage caused by low energy alpha particles. These particles are NOT detected by ordinary geiger
counters. A special alpha particle detector is required to detect alpha particles; these particles are stopped by a sheet of paper. Gieger counter
tubes are usually made of metal which alpha particles cannot penetrate.
Dusty materials emitting alpha particles are caught by lung tissue when inhaled. After embedding in the lungs, dust particles continue to give off
alpha radiation for many years causing on-going damage and mutating DNA, ultimately causing lung cancer. It's worth noting however, that when alpha
particles are present beta and gamma are usually also present, which are readily detectable by a geiger counter.
The Reactor is at 200 svh...Not good
