The maximum yield of the W54 warhead used in this deivce  was 1 kt (1000 tonnes of TNT.)

When activated after pressing a serious of buttons the user will have form one minute to one hour to remote detonate the bomb using the enclosed trigger device.

The device will do 50000 hps of damage to anyone or anything caught in it's blast radius of two miles.

Effects

External radiation occurs when either part of or all of the body is exposed from an external source, such as when a person is standing near the site of where a radiological device such as a suitcase bomb or suitcase nuke is set off and he or she is exposed to radiation, which can be absorbed by the body or can pass completely through it.

Contamination occurs when radioactive materials in the form of solids, liquids or gases are released into the air and contaminate people externally, internally or both. This happens when body parts such as the skin become contaminated and/or if the harmful material gets inside the body via the lungs, gut or wounds.

Incorporation of radioactive material occurs when body cells, tissues and organs such as bone, liver, thyroid or kidney, are contaminated.

Gamma radiation can travel many meters in the air and many centimeters once in human tissue; therefore they represent a major external threat. Dense material is needed as a shield. Beta radiation can travel meters in air and can moderately penetrate human skin, but clothing and some protection can help. Alpha radiation travels a very short distance through the air and can't penetrate the skin, but can be harmful if inhaled, swallowed or absorbed through open wounds.

Radiation in the first hour after an explosion is about 90 percent, with it going down to about 1 percent of the original level after two days. Radiation only drops to trace levels after 300 hours.

Symptoms

People in the immediate vicinity of a suitcase nuke or suitcase bomb detonation would likely die from the force of the conventional explosion itself. Some survivors of the blast might die of radiation poisoning in the weeks afterward. Those farther away from the explosion might suffer radiation sickness in the days and weeks afterward, but recover. Over time, risks of cancer in the affected area would rise, but perhaps only slightly.

A mix of physical symptoms must be used to judge the seriousness of exposure. Impact of radiation poisoning also changes if the body has experienced burns or physical trauma. In the case of treatable victims, extensive medical treatment may be needed for more than two months after exposure.

Some symptoms may include vomiting, headache, fatigue, weakness, diarrhea, thermal burn-like skin effects, secondary infections, reoccurring bleeding and hair loss.
